The mailposts.php script allows a site administrator to configure PmWiki to send email messages whenever pages are changed on the wiki site. MailPosts 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 MailPosts feature is especially useful for sites that have infrequent updates, eliminating the need to frequently check RecentChanges 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 MailPosts:
$EnableMailPosts=1; # to enable mailposts
$MailPostsTo="firstname.lastname@example.org"; # where to send mail
$MailPostsDelay=1800; # wait 30+ min after initial post
$MailPostsSquelch=7200; # require 2+ hours between mails
$MailPostsTo 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.
$MailPostsDelay 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.
$MailPostsSquelch 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
$MailPostsDelay is set to a small value.
The defaults for
$MailPostsSquelch 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 MailPosts are given below, and also described in the mailposts.php script.
Sites running PHP under Windows may not have PHP's mail function configured correctly. Such sites may need to add a line like
to config.php, where smtp.server.com is the name of your host's preferred outgoing mail server.
