    1 = Email Notification of Ticket Changes =
    2 [[TracGuideToc]]
    3 
    4 Trac supports notification of ticket changes via email.
    5 
    6 Email 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.
    7 
    8 Disabled by default, notification can be activated and configured in [wiki:TracIni trac.ini].
    9 
    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.
    20 
    21 == Configuring SMTP Notification ==
    22 
    23 '''Important:''' For TracNotification to work correctly, the `[trac] base_url` option must be set in [wiki:TracIni trac.ini].
    24 
    25 === Configuration Options ===
    26 These are the available options for the `[notification]` section in trac.ini.
    27 
    28  * '''`smtp_enabled`''': Enable email notification.
    29  * '''`smtp_from`''': Email address to use for ''Sender''-headers in notification emails.
    30  * '''`smtp_from_name`''': Sender name to use for ''Sender''-headers in notification emails.
    31  * '''`smtp_replyto`''': Email address to use for ''Reply-To''-headers in notification emails.
    32  * '''`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.
    33  * '''`smtp_always_cc`''': List of email addresses to always send notifications to. ''Typically used to post ticket changes to a dedicated mailing list.''
    34  * '''`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
    35  * '''`smtp_subject_prefix`''': (''since 0.10.1'') Text that is inserted before the subject of the email. Set to "!__default!__" by default.
    36  * '''`always_notify_reporter`''':  Always send notifications to any address in the reporter field (default: false).
    37  * '''`always_notify_owner`''': (''since 0.9'') Always send notifications to the address in the owner field (default: false).
    38  * '''`always_notify_updater`''': (''since 0.10'') Always send a notification to the updater of a ticket (default: true).
    39  * '''`use_public_cc`''': (''since 0.10'') Addresses in To: (owner, reporter) and Cc: lists are visible by all recipients (default is ''Bcc:'' - hidden copy).
    40  * '''`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.
    41  * '''`mime_encoding`''': (''since 0.10'') This option allows selecting the MIME encoding scheme. Supported values:
    42    * `none`: default value, uses 7bit encoding if the text is plain ASCII, or 8bit otherwise.
    43    * `base64`: works with any kind of content. May cause some issues with touchy anti-spam/anti-virus engines.
    44    * `qp` or `quoted-printable`: best for european languages (more compact than base64) if 8bit encoding cannot be used.
    45  * '''`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.
    46  * '''`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:
    47    * `SmtpEmailSender`: connects to an SMTP server (default).
    48    * `SendmailEmailSender`: runs a `sendmail`-compatible executable.
    49 
    50 Either '''`smtp_from`''' or '''`smtp_replyto`''' (or both) ''must'' be set, otherwise Trac refuses to send notification mails.
    51 
    52 The following options are specific to email delivery through SMTP.
    53  * '''`smtp_server`''': SMTP server used for notification messages.
    54  * '''`smtp_port`''': (''since 0.9'') Port used to contact the SMTP server.
    55  * '''`smtp_user`''': (''since 0.9'') User name for authentication SMTP account.
    56  * '''`smtp_password`''': (''since 0.9'') Password for authentication SMTP account.
    57  * '''`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.
    58 
    59 The following option is specific to email delivery through a `sendmail`-compatible executable.
    60  * '''`sendmail_path`''': (''since 0.12'') Path to the sendmail executable. The sendmail program must accept the `-i` and `-f` options.
    61 
    62 === Example Configuration (SMTP) ===
    63 {{{
    64 [notification]
    65 smtp_enabled = true
    66 smtp_server = mail.example.com
    67 smtp_from = notifier@example.com
    68 smtp_replyto = myproj@projects.example.com
    69 smtp_always_cc = ticketmaster@example.com, theboss+myproj@example.com
    70 }}}
    71 
    72 === Example Configuration (`sendmail`) ===
    73 {{{
    74 [notification]
    75 smtp_enabled = true
    76 email_sender = SendmailEmailSender
    77 sendmail_path = /usr/sbin/sendmail
    78 smtp_from = notifier@example.com
    79 smtp_replyto = myproj@projects.example.com
    80 smtp_always_cc = ticketmaster@example.com, theboss+myproj@example.com
    81 }}}
    82 
    83 === Customizing the e-mail subject ===
    84 The 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:
    85 {{{
    86 $prefix #$ticket.id: $summary
    87 }}}
    88 The following variables are available in the template:
    89 
    90  * `env`: The project environment (see [trac:source:/trunk/trac/env.py env.py]).
    91  * `prefix`: The prefix defined in `smtp_subject_prefix`.
    92  * `summary`: The ticket summary, with the old value if the summary was edited.
    93  * `ticket`: The ticket model object (see [trac:source:/trunk/trac/ticket/model.py model.py]). Individual ticket fields can be addressed by appending the field name separated by a dot, e.g. `$ticket.milestone`.
    94 
    95 === Customizing the e-mail content ===
    96 
    97 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:
    98 
    99 {{{
    100 $ticket_body_hdr
    101 $ticket_props
    102 #choose ticket.new

    157 }}}
    158 
    159 == Using GMail as the SMTP relay host ==
    160 
    161 Use the following configuration snippet
    162 {{{
    163 [notification]
    164 smtp_enabled = true
    165 use_tls = true
    166 mime_encoding = base64
    167 smtp_server = smtp.gmail.com
    168 smtp_port = 587
    169 smtp_user = user
    170 smtp_password = password
    171 }}}
    172 
    173 where ''user'' and ''password'' match an existing GMail account, ''i.e.'' the ones you use to log in on [http://gmail.com]
    174 
    175 Alternatively, you can use `smtp_port = 25`.[[br]]
    176 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.
    177  
    178 == Filtering notifications for one's own changes ==
    179 In Gmail, use the filter:
    180 
    181 {{{
    182 from:(<smtp_from>) (("Reporter: <username>" -Changes) OR "Changes (by <username>)")
    183 }}}
    184 
    185 For Trac .10, use the filter:
    186 {{{
    187 from:(<smtp_from>) (("Reporter: <username>" -Changes -Comment) OR "Changes (by <username>)" OR "Comment (by <username>)")
    188 }}}
    189 
    190 to delete these notifications.
    191 
    192 In Thunderbird, there is no such solution if you use IMAP
    193 (see http://kb.mozillazine.org/Filters_(Thunderbird)#Filtering_the_message_body).
    194 
    195 The best you can do is to set "always_notify_updater" in conf/trac.ini to false.
    196 You will however still get an email if you comment a ticket that you own or have reported.
    197 
    198 You can also add this plugin:
    199 http://trac-hacks.org/wiki/NeverNotifyUpdaterPlugin
    200 
    201 == Troubleshooting ==
    202 
    203 If 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.
    204 
    205 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.
    206 
    207 === ''Permission denied'' error ===
    208 
    209 Typical error message:
    210 {{{
    211   ...
    212   File ".../smtplib.py", line 303, in connect
    213     raise socket.error, msg
    214   error: (13, 'Permission denied')
    215 }}}
    216 
    217 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.
    218 
    219 Many users get confused when their manual attempts to contact the SMTP server succeed:
    220 {{{
    221 telnet localhost 25
    222 }}}
    223 The trouble is that a regular user may connect to the SMTP server, but the web server cannot:
    224 {{{
    225 sudo -u www-data telnet localhost 25
    226 }}}
    227 
    228 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.
    229 
    230 Relevant ML threads:
    231  * SELinux: http://article.gmane.org/gmane.comp.version-control.subversion.trac.general/7518
    232 
    233 For SELinux in Fedora 10:
    234 {{{
    235 $ setsebool -P httpd_can_sendmail 1
    236 }}}
    237 === ''Suspected spam'' error ===
    238 
    239 Some SMTP servers may reject the notification email sent by Trac.
    240 
    241 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.
    242 
    243 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.
    244 
    245 === ''501, 5.5.4 Invalid Address'' error ===
    246 
    247 On IIS 6.0 you could get a
    248 {{{
    249 Failure sending notification on change to ticket #1: SMTPHeloError: (501, '5.5.4 Invalid Address')
    250 }}}
    251 in the trac log. Have a look [http://support.microsoft.com/kb/291828 here] for instructions on resolving it.
