  • TracNotification

    v1 v1  
     1= Email Notification of Ticket Changes =
     4Trac supports notification of ticket changes via email.
     6Email notification is useful to keep users up-to-date on tickets/issues of interest, and also provides a convenient way to post all ticket changes to a dedicated mailing list. For example, this is how the [ Trac-tickets] mailing list is set up.
     8Disabled by default, notification can be activated and configured in [wiki:TracIni trac.ini].
     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.
     13=== How to use your username to receive notification mails ===
     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.
     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.
     19When 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`''').
     21=== Ticket attachment notifications
     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:
     26trac.ticket.notification.TicketAttachmentNotifier = disabled
     29== Configuring SMTP Notification ==
     31'''Important:''' For TracNotification to work correctly, the `[trac] base_url` option must be set in [wiki:TracIni trac.ini].
     33=== Configuration Options ===
     34These are the available options for the `[notification]` section in trac.ini:
     38=== Example Configuration (SMTP) ===
     41smtp_enabled = true
     42smtp_server =
     43smtp_from =
     44smtp_replyto =
     45smtp_always_cc =,
     48=== Example Configuration (`sendmail`) ===
     51smtp_enabled = true
     52email_sender = SendmailEmailSender
     53sendmail_path = /usr/sbin/sendmail
     54smtp_from =
     55smtp_replyto =
     56smtp_always_cc =,
     59=== Customizing the e-mail subject ===
     60The e-mail subject can be customized with the `ticket_subject_template` option, which contains a [ Genshi text template] snippet. The default value is:
     62$prefix #$ $summary
     64The following variables are available in the template:
     66 * `env`: The project environment (see [trac:source:/trunk/trac/]).
     67 * `prefix`: The prefix defined in `smtp_subject_prefix`.
     68 * `summary`: The ticket summary, with the old value if the summary was edited.
     69 * `ticket`: The ticket model object (see [trac:source:/trunk/trac/ticket/]). Individual ticket fields can be addressed by appending the field name separated by a dot, eg `$ticket.milestone`.
     71=== Customizing the e-mail content ===
     73The 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:
     78{% choose %}\
     79{%   when True %}\
     81{%   end %}\
     82{%   otherwise %}\
     83{%     if changes_body %}\
     84${_('Changes (by %(author)s):',}
     87{%     end %}\
     88{%     if changes_descr %}\
     89{%       if not changes_body and not change.comment and %}\
     90${_('Description changed by %(author)s:',}
     91{%       end %}\
     94{%     end %}\
     95{%     if change.comment %}\
     97${changes_body and _('Comment:') or _('Comment (by %(author)s):',}
     100{%     end %}\
     101{%   end %}\
     102{% end %}\
     105${_('Ticket URL: <%(link)s>',}
     106$ <${project.url or abs_href()}>

     136== Customizing e-mail content for MS Outlook ==
     138MS Outlook normally presents plain text e-mails with a variable-width font, and as a result 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].
     140Replace the following second row in the template:
     145with this (requires Python 2.6 or later):
     148{% with
     149   pv = [(a[0].strip(), a[1].strip()) for a in [b.split(':') for b in
     150         [c.strip() for c in
     151          ticket_props.replace('|', '\n').splitlines()[1:-1]] if ':' in b]];
     152   sel = ['Reporter', 'Owner', 'Type', 'Status', 'Priority', 'Milestone',
     153          'Component', 'Severity', 'Resolution', 'Keywords'] %}\
     154${'\n'.join('%s\t%s' % (format(p[0]+':', ' <12'), p[1]) for p in pv if p[0] in sel)}
     155{% end %}\
     159The table of ticket properties is replaced with a list of a selection of the properties. A tab character separates the name and value in such a way that most people should find this more pleasing than the default table when using MS Outlook.

     195**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:
     197   sel = ['Reporter', ..., 'Keywords', 'Custom1', 'Custom2']
     200However, the solution is still a workaround to an automatically HTML-formatted e-mail.
     202== Using GMail as the SMTP relay host ==
     204Use the following configuration snippet:
     207smtp_enabled = true
     208use_tls = true
     209mime_encoding = base64
     210smtp_server =
     211smtp_port = 587
     212smtp_user = user
     213smtp_password = password
     216where ''user'' and ''password'' match an existing GMail account, ie the ones you use to log in on [].
     218Alternatively, you can use `smtp_port = 25`.[[br]]
     219You 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.
     221== Filtering notifications for one's own changes and comments ==
     222In Gmail, use the filter:
     224from:(<smtp_from>) (("Reporter: <username>" -Changes -Comment) OR "Changes (by <username>)" OR "Comment (by <username>)")
     227to delete these notifications.
     229In Thunderbird, there is no such solution if you use IMAP, see
     231You can also add this plugin:
     232, or vote for [trac:#2247] to be fixed.
     234== Troubleshooting ==
     236If 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.
     238Notification 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.
     240=== ''Permission denied'' error ===
     242Typical error message:
     244  ...
     245  File ".../", line 303, in connect
     246    raise socket.error, msg
     247  error: (13, 'Permission denied')
     250This error usually comes from a security settings on the server: many Linux distributions do not allow the web server (Apache, ...) to post email messages to the local SMTP server.
     252Many users get confused when their manual attempts to contact the SMTP server succeed:
     254telnet localhost 25
     256This is because a regular user may connect to the SMTP server, but the web server cannot:
     258sudo -u www-data telnet localhost 25
     261In 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 in the Trac [trac:MailingList MailingList] archive.
     263Relevant ML threads:
     264 * SELinux:
     266For SELinux in Fedora 10:
     268$ setsebool -P httpd_can_sendmail 1
     271=== ''Suspected spam'' error ===
     273Some SMTP servers may reject the notification email sent by Trac.
     275The 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, change the default encoding to "quoted-printable" using the `mime_encoding` option.
     277Quoted printable encoding works better with languages that use one of the Latin charsets. For Asian charsets, stick with the Base64 encoding.
