    33
     
    88Disabled by default, notification can be activated and configured in [wiki:TracIni trac.ini].
    99
    10 == Receiving Notification Mails ==
    11 When reporting a new ticket or adding a comment, enter a valid email address or your username in the ''reporter'', ''assigned to/owner'' or ''cc'' field. Trac will automatically send you an email when changes are made to the ticket (depending on how notification is configured).
    12 
    13 This is useful to keep up-to-date on an issue or enhancement request that interests you.
    14 
    15 === How to use your username to receive notification mails ===
    16 
    17 To receive notification mails, you can either enter a full email address or your username. To get notified with a simple username or login, you need to specify a valid email address in the ''Preferences'' page.
    18 
    19 Alternatively, a default domain name ('''`smtp_default_domain`''') can be set in the TracIni file (see [#ConfigurationOptions Configuration Options] below). In this case, the default domain will be appended to the username, which can be useful for an "Intranet" kind of installation.
     10== Receiving Notification Mails
     11When reporting a new ticket or adding a comment, enter a valid email address or your Trac username in the ''reporter'', ''assigned to/owner'' or ''cc'' field. Trac will automatically send you an email when changes are made to the ticket, depending on how notification is configured.
     12
     13=== How to use your username to receive notification mails
     14
     15To receive notification mails, you can either enter a full email address or your Trac username. To get notified with a simple username or login, you need to specify a valid email address in the ''Preferences'' page.
     16
     17Alternatively, a default domain name ('''`smtp_default_domain`''') can be set in the TracIni file, see [#ConfigurationOptions Configuration Options] below. In this case, the default domain will be appended to the username, which can be useful for an "Intranet" kind of installation.
    2018
    2119When using apache and mod_kerb for authentication against Kerberos / Active Directory, usernames take the form ('''`username@EXAMPLE.LOCAL`'''). To avoid this being interpreted as an email address, add the Kerberos domain to  ('''`ignore_domains`''').
    2220
    23 == Configuring SMTP Notification ==
     21=== Ticket attachment notifications
     22
     23Since 1.0.3 Trac will send notifications when a ticket attachment is added or deleted. Usually attachment notifications will be enabled in an environment by default. To disable the attachment notifications for an environment the `TicketAttachmentNotifier` component must be disabled:
     24{{{#!ini
     25[components]
     26trac.ticket.notification.TicketAttachmentNotifier = disabled
     27}}}
     28
     29== Configuring SMTP Notification
    2430
    2531'''Important:''' For TracNotification to work correctly, the `[trac] base_url` option must be set in [wiki:TracIni trac.ini].
    2632
    27 === Configuration Options ===
    28 These are the available options for the `[notification]` section in trac.ini.
    29 
    30  * '''`smtp_enabled`''': Enable email notification.
    31  * '''`smtp_from`''': Email address to use for ''Sender''-headers in notification emails.
    32  * '''`smtp_from_name`''': Sender name to use for ''Sender''-headers in notification emails.
    33  * '''`smtp_replyto`''': Email address to use for ''Reply-To''-headers in notification emails.
    34  * '''`smtp_default_domain`''': (''since 0.10'') Append the specified domain to addresses that do not contain one. Fully qualified addresses are not modified. The default domain is appended to all username/login for which an email address cannot be found from the user settings.
    35  * '''`smtp_always_cc`''': List of email addresses to always send notifications to. ''Typically used to post ticket changes to a dedicated mailing list.''
    36  * '''`smtp_always_bcc`''': (''since 0.10'') List of email addresses to always send notifications to, but keeps addresses not visible from other recipients of the notification email
    37  * '''`smtp_subject_prefix`''': (''since 0.10.1'') Text that is inserted before the subject of the email. Set to "!__default!__" by default.
    38  * '''`always_notify_reporter`''':  Always send notifications to any address in the reporter field (default: false).
    39  * '''`always_notify_owner`''': (''since 0.9'') Always send notifications to the address in the owner field (default: false).
    40  * '''`always_notify_updater`''': (''since 0.10'') Always send a notification to the updater of a ticket (default: true).
    41  * '''`use_public_cc`''': (''since 0.10'') Addresses in To: (owner, reporter) and Cc: lists are visible by all recipients (default is ''Bcc:'' - hidden copy).
    42  * '''`use_short_addr`''': (''since 0.10'') Enable delivery of notifications to addresses that do not contain a domain (i.e. do not end with ''@<domain.com>'').This option is useful for intranets, where the SMTP server can handle local addresses and map the username/login to a local mailbox. See also `smtp_default_domain`. Do not use this option with a public SMTP server.
    43  * '''`ignore_domains`''': Comma-separated list of domains that should not be considered part of email addresses (for usernames with Kerberos domains).
    44  * '''`mime_encoding`''': (''since 0.10'') This option allows selecting the MIME encoding scheme. Supported values:
    45    * `none`: default value, uses 7bit encoding if the text is plain ASCII, or 8bit otherwise.
    46    * `base64`: works with any kind of content. May cause some issues with touchy anti-spam/anti-virus engines.
    47    * `qp` or `quoted-printable`: best for european languages (more compact than base64) if 8bit encoding cannot be used.
    48  * '''`ticket_subject_template`''': (''since 0.11'') A [http://genshi.edgewall.org/wiki/Documentation/text-templates.html Genshi text template] snippet used to get the notification subject.
    49  * '''`email_sender`''': (''since 0.12'') Name of the component implementing `IEmailSender`. This component is used by the notification system to send emails. Trac currently provides the following components:
    50    * `SmtpEmailSender`: connects to an SMTP server (default).
    51    * `SendmailEmailSender`: runs a `sendmail`-compatible executable.   
    52 
    53 Either '''`smtp_from`''' or '''`smtp_replyto`''' (or both) ''must'' be set, otherwise Trac refuses to send notification mails.
    54 
    55 The following options are specific to email delivery through SMTP.
    56  * '''`smtp_server`''': SMTP server used for notification messages.
    57  * '''`smtp_port`''': (''since 0.9'') Port used to contact the SMTP server.
    58  * '''`smtp_user`''': (''since 0.9'') User name for authentication SMTP account.
    59  * '''`smtp_password`''': (''since 0.9'') Password for authentication SMTP account.
    60  * '''`use_tls`''': (''since 0.10'') Toggle to send notifications via a SMTP server using [http://en.wikipedia.org/wiki/Transport_Layer_Security TLS], such as GMail.
    61 
    62 The following option is specific to email delivery through a `sendmail`-compatible executable.
    63  * '''`sendmail_path`''': (''since 0.12'') Path to the sendmail executable. The sendmail program must accept the `-i` and `-f` options.
    64 
    65 === Example Configuration (SMTP) ===
    66 {{{
     33=== Configuration Options
     34These are the available options for the `[notification]` section in trac.ini:

    8558
    86 === Customizing the e-mail subject ===
     59=== Subscriber Configuration
     60The default subscriptions are configured in the `[notification-subscriber]` section in trac.ini:
     61
     62[[TracIni(notification-subscriber)]]
     63
     64Each user can override these defaults in his ''Notifications'' preferences.
     65
     66For example to unsubscribe from notifications for one's own changes and comments, the rule "Never notify: I update a ticket" should be added above other subscription rules.
     67
     68=== Customizing the e-mail subject
    8769The e-mail subject can be customized with the `ticket_subject_template` option, which contains a [http://genshi.edgewall.org/wiki/Documentation/text-templates.html Genshi text template] snippet. The default value is:
    88 {{{
     70{{{#!genshi
    8971$prefix #$ticket.id: $summary
    9072}}}
     
    9476 * `prefix`: The prefix defined in `smtp_subject_prefix`.
    9577 * `summary`: The ticket summary, with the old value if the summary was edited.
    96  * `ticket`: The ticket model object (see [trac:source:/trunk/trac/ticket/model.py model.py]). Individual ticket fields can be addressed by appending the field name separated by a dot, e.g. `$ticket.milestone`.
    97 
    98 === Customizing the e-mail content ===
    99 
    100 The notification e-mail content is generated based on `ticket_notify_email.txt` in `trac/ticket/templates`.  You can add your own version of this template by adding a `ticket_notify_email.txt` to the templates directory of your environment. The default looks like this:

    164 
    165 Out-of-the-box, MS Outlook normally presents plain text e-mails with a variable-width font; the ticket properties table will most certainly look like a mess in MS Outlook. This can be fixed with some customization of the [#Customizingthee-mailcontent e-mail template].

    222 However, it's not as perfect as an HTML formatted e-mail would be, but presented ticket properties are at least readable...
    223 
    224 
    225 == Using GMail as the SMTP relay host ==
    226 
    227 Use the following configuration snippet
    228 {{{
     204**Important**: Only those ticket fields that are listed in `sel` are part of the HTML mail. If you have defined custom ticket fields which are to be part of the mail, then they have to be added to `sel`. Example:
     205{{{
     206   sel = ['Reporter', ..., 'Keywords', 'Custom1', 'Custom2']
     207}}}
     208
     209However, the solution is still a workaround to an automatically HTML-formatted e-mail.
     210
     211== Using GMail as the SMTP relay host
     212
     213Use the following configuration snippet:
     214{{{#!ini
    229215[notification]
    230216smtp_enabled = true
     
    237223}}}
    238224
    239 where ''user'' and ''password'' match an existing GMail account, ''i.e.'' the ones you use to log in on [http://gmail.com]
     225where ''user'' and ''password'' match an existing GMail account, ie the ones you use to log in on [http://gmail.com].
    240226
    241227Alternatively, you can use `smtp_port = 25`.[[br]]
    242 You should not use `smtp_port = 465`. It will not work and your ticket submission may deadlock. Port 465 is reserved for the SMTPS protocol, which is not supported by Trac. See [comment:ticket:7107:2 #7107] for details.
    243  
    244 == Filtering notifications for one's own changes ==
    245 In Gmail, use the filter:
    246 
    247 {{{
    248 from:(<smtp_from>) (("Reporter: <username>" -Changes) OR "Changes (by <username>)")
    249 }}}
    250 
    251 For Trac .10, use the filter:
    252 {{{
    253 from:(<smtp_from>) (("Reporter: <username>" -Changes -Comment) OR "Changes (by <username>)" OR "Comment (by <username>)")
    254 }}}
    255 
    256 to delete these notifications.
    257 
    258 In Thunderbird, there is no such solution if you use IMAP
    259 (see http://kb.mozillazine.org/Filters_(Thunderbird)#Filtering_the_message_body).
    260 
    261 The best you can do is to set "always_notify_updater" in conf/trac.ini to false.
    262 You will however still get an email if you comment a ticket that you own or have reported.
    263 
    264 You can also add this plugin:
    265 http://trac-hacks.org/wiki/NeverNotifyUpdaterPlugin
    266 
    267 == Troubleshooting ==
     228You should not use `smtp_port = 465`. Doing so may deadlock your ticket submission. Port 465 is reserved for the SMTPS protocol, which is not supported by Trac. See [trac:comment:2:ticket:7107 #7107] for details.
     229
     230== Troubleshooting
    268231
    269232If you cannot get the notification working, first make sure the log is activated and have a look at the log to find if an error message has been logged. See TracLogging for help about the log feature.
    270233
    271 Notification errors are not reported through the web interface, so the user who submit a change or a new ticket never gets notified about a notification failure. The Trac administrator needs to look at the log to find the error trace.
    272 
    273 === ''Permission denied'' error ===
     234Notification errors are not reported through the web interface, so the user who submits a change or a new ticket never gets notified about a notification failure. The Trac administrator needs to look at the log to find the error trace.
     235
     236=== ''Permission denied'' error
    274237
    275238Typical error message:

    281244}}}
    282245
    283 This error usually comes from a security settings on the server: many Linux distributions do not let the web server (Apache, ...) to post email message to the local SMTP server.

    284247
    285248Many users get confused when their manual attempts to contact the SMTP server succeed:
    286 {{{
     249{{{#!sh
    287250telnet localhost 25
    288251}}}
    289 The trouble is that a regular user may connect to the SMTP server, but the web server cannot:

     252This is because a regular user may connect to the SMTP server, but the web server cannot:

    291254sudo -u www-data telnet localhost 25
    292255}}}
    293256
    294 In such a case, you need to configure your server so that the web server is authorized to post to the SMTP server. The actual settings depend on your Linux distribution and current security policy. You may find help browsing the Trac [trac:MailingList MailingList] archive.

     267=== ''Suspected spam'' error
    304268
    305269Some SMTP servers may reject the notification email sent by Trac.
    306270
    307 The default Trac configuration uses Base64 encoding to send emails to the recipients. The whole body of the email is encoded, which sometimes trigger ''false positive'' SPAM detection on sensitive email servers. In such an event, it is recommended to change the default encoding to "quoted-printable" using the `mime_encoding` option.
    308 
    309 Quoted printable encoding works better with languages that use one of the Latin charsets. For Asian charsets, it is recommended to stick with the Base64 encoding.
    310 
    311 === ''501, 5.5.4 Invalid Address'' error ===
    312

    315 Failure sending notification on change to ticket #1: SMTPHeloError: (501, '5.5.4 Invalid Address')
    316 }}}
