    4 Trac supports notification about ticket changes via email.
     4Trac supports notification of ticket changes via email.
    55
    66Email 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 [http://lists.edgewall.com/archive/trac-tickets/ Trac-tickets] mailing list is set up.
     
    99
    1010== Receiving Notification Mails ==
    11 When reporting a new ticket or adding a comment, enter a valid email address 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.
     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.
     18
     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`''').
     20
     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}}}
    1428
    1529== Configuring SMTP Notification ==
    1630
     31'''Important:''' For TracNotification to work correctly, the `[trac] base_url` option must be set in [wiki:TracIni trac.ini].
     32
    1733=== Configuration Options ===
    18 These are the available options for the ''[notification]'' section in trac.ini.
    19  * '''smtp_enabled''': Enable email notification.
    20  * '''smtp_server''': SMTP server used for notification messages.
    21  * '''smtp_user''': (''since 0.9'') User name for authentication SMTP account.
    22  * '''smtp_password''': (''since 0.9'') Password for authentication SMTP account.
    23  * '''smtp_from''': Email address to use for ''Sender''-headers in notification emails.
    24  * '''smtp_replyto''': Email address to use for ''Reply-To''-headers in notification emails.
    25  * '''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.
    26  * '''smtp_always_cc''': List of email addresses to always send notifications to. ''Typically used to post ticket changes to a dedicated mailing list.''
    27  * '''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
    28  * '''always_notify_reporter''':  Always send notifications to any address in the reporter field.
    29  * '''always_notify_owner''': (''since 0.9'') Always send notifications to the address in the owner field.
    30  * '''always_notify_updater''': (''since 0.10'') Always send a notification to the updater of a ticket.
    31  * '''use_public_cc''': (''since 0.10'') Addresses in To: (owner, reporter) and Cc: lists are visible by all recipients (default is ''Bcc:'' - hidden copy).
    32  * '''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.
    33  * '''mime_encoding''': (''since 0.10'') E-mail notifications are always sent in 7-bit mode. This option allows to select the MIME encoding scheme. Supported values:
    34    * `base64`: default value, works with any kind of content. May cause some issues with touchy anti-spam/anti-virus engines.
    35    * `qp` or `quoted-printable`: best for european languages (more compact than base64), not recommended for non-ASCII text (less compact than base64)
    36    * `none`: no encoding. Use with plain english only (ASCII). E-mails with non-ASCII chars won't be delivered.
    37 
    38 Either '''smtp_from''' or '''smtp_replyto''' (or both) ''must'' be set, otherwise Trac refuses to send notification mails.
    39 
    40 === Example Configuration ===
    41 
     34These are the available options for the `[notification]` section in trac.ini:
     35
     36[[TracIni(notification)]]
     37
     38=== Example Configuration (SMTP) ===
    4239{{{
    4340[notification]
     
    4744smtp_replyto = myproj@projects.example.com
    4845smtp_always_cc = ticketmaster@example.com, theboss+myproj@example.com
     46}}}
     47
     48=== Example Configuration (`sendmail`) ===
     49{{{
     50[notification]
     51smtp_enabled = true
     52email_sender = SendmailEmailSender
     53sendmail_path = /usr/sbin/sendmail
     54smtp_from = notifier@example.com
     55smtp_replyto = myproj@projects.example.com
     56smtp_always_cc = ticketmaster@example.com, theboss+myproj@example.com
     57}}}
     58
     59=== Customizing the e-mail subject ===
     60The 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:
     61{{{
     62$prefix #$ticket.id: $summary
     63}}}
     64The following variables are available in the template:
     65
     66 * `env`: The project environment (see [trac:source:/trunk/trac/env.py env.py]).
     67 * `prefix`: The prefix defined in `smtp_subject_prefix`.
     68 * `summary`: The ticket summary, with the old value if the summary was edited.
     69 * `ticket`: The ticket model object (see [trac:source:/trunk/trac/ticket/model.py model.py]). Individual ticket fields can be addressed by appending the field name separated by a dot, eg `$ticket.milestone`.
     70
     71=== Customizing the e-mail content ===
     72
     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:
     74
     75{{{
     76$ticket_body_hdr
     77$ticket_props
     78{% choose ticket.new %}\
     79{%   when True %}\
     80$ticket.description
     81{%   end %}\
     82{%   otherwise %}\
     83{%     if changes_body %}\
     84${_('Changes (by %(author)s):', author=change.author)}
     85
     86$changes_body
     87{%     end %}\
     88{%     if changes_descr %}\
     89{%       if not changes_body and not change.comment and change.author %}\
     90${_('Description changed by %(author)s:', author=change.author)}
     91{%       end %}\
     92$changes_descr
     93--
     94{%     end %}\
     95{%     if change.comment %}\
     96
     97${changes_body and _('Comment:') or _('Comment (by %(author)s):', author=change.author)}
     98
     99$change.comment
     100{%     end %}\
     101{%   end %}\
     102{% end %}\
     103

     136== Customizing e-mail content for MS Outlook ==
     137
     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].
     139
     140Replace the following second row in the template:
     141{{{
     142$ticket_props
     143}}}
     144
     145with this (requires Python 2.6 or later):
     146{{{
     147--------------------------------------------------------------------------
     148{% with
     149   pv = [(a[0].strip(), a[1].strip()) for a in [b.split(':') for b in
     150         [c.strip() for c in
     151          ticket_props.replace('|', '\n').splitlines()[1:-1]] if ':' in b]];
     152   sel = ['Reporter', 'Owner', 'Type', 'Status', 'Priority', 'Milestone',
     153          'Component', 'Severity', 'Resolution', 'Keywords'] %}\
     154${'\n'.join('%s\t%s' % (format(p[0]+':', ' <12'), p[1]) for p in pv if p[0] in sel)}
     155{% end %}\
     156--------------------------------------------------------------------------
     157}}}
     158
     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:
     196{{{
     197   sel = ['Reporter', ..., 'Keywords', 'Custom1', 'Custom2']
     198}}}
     199
     200However, the solution is still a workaround to an automatically HTML-formatted e-mail.
     201
     202== Using GMail as the SMTP relay host ==
     203
     204Use the following configuration snippet:
     205{{{
     206[notification]
     207smtp_enabled = true
     208use_tls = true
     209mime_encoding = base64
     210smtp_server = smtp.gmail.com
     211smtp_port = 587
     212smtp_user = user
     213smtp_password = password
     214}}}
     215
     216where ''user'' and ''password'' match an existing GMail account, ie the ones you use to log in on [http://gmail.com].
     217
     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.
     220 
     221== Filtering notifications for one's own changes and comments ==
     222In Gmail, use the filter:
     223{{{
     224from:(<smtp_from>) (("Reporter: <username>" -Changes -Comment) OR "Changes (by <username>)" OR "Comment (by <username>)")
     225}}}
     226
     227to delete these notifications.
     228
     229In Thunderbird, there is no such solution if you use IMAP, see http://kb.mozillazine.org/Filters_(Thunderbird)#Filtering_the_message_body.
     230
     231You can also add this plugin:
     232http://trac-hacks.org/wiki/NeverNotifyUpdaterPlugin, or vote for [trac:#2247] to be fixed.
     233
    77234== Troubleshooting ==
    78235
    79236If 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.
    80237
    81 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.

    103260
    104 In such a case, you need to configure your server so that the web server is authorize 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 MailingList archive.

    113 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.
    114 
    115 Quoted printable enconding works better with languages that use one of the Latin charsets. For Asian charsets, it is recommended to stick with the Base64 encoding.
