script allows a site administrator to configure Pm Wiki
to send email messages whenever pages are changed on the wiki site. Mail Posts
can be configured so that multiple page changes over a short period of time are combined into a single email message (to avoid flooding a mailbox).
The Mail Posts
feature is especially useful for sites that have infrequent updates, eliminating the need to frequently check Recent Changes
pages just to see if anything has changed.
Full configuration details are available in scripts/mailposts.php
, but here's the brief synopsis of what needs to go in config.php or a per-group customization script for Mail Posts
$EnableMailPosts=1; # to enable mailposts
$MailPostsTo="[email protected]"; # where to send mail
$MailPostsDelay=1800; # wait 30+ min after initial post
$MailPostsSquelch=7200; # require 2+ hours between mails
may be a comma-separated list of addresses if multiple recipients are desired.
Since an initial post is often followed by several posts containing minor edits, it's useful to wait a short period of time before sending an email.
is the minimum amount of time that must elapse from an initial post before a message is sent. Any additional posts occuring during the delay period are included in the message when it is sent. The message is sent on the first execution of pmwiki.php after the delay period has expired (which for inactive sites could be much longer than the delay period). A delay of zero means to immediately send a message whenever an update is received.
specifies the minimum amount of time that must elapse before sending another notification message. This is useful to prevent large number of rapid-succession messages if
is set to a small value.
The defaults for
are 0 and 7200. With these values, an email is sent as soon as a page is changed, and subsequent changes are "held" for at least two hours before being sent in another message.
The variables used to control Mail Posts
are given below
, and also described in the mailposts.php
Note for Windows installations
Sites running PHP under Windows may not have PHP's mail
[http://www.php.net/mail] function configured correctly. Such sites may need to add a line like
, where smtp.server.com
is the name of your host's preferred outgoing mail server.
