Mail logger plugin

This plugin can be used to log several actions done in a mail session:

Setting and removing \Deleted flag
Expunging
Copying mails to another mailbox
Mailbox creations
Mailbox deletions
Mailbox renames
Any flag changes
Saves

Messages' UID and Message-ID header is logged for each action. Here's an example:

imap(user): copy -> Trash: uid=908, msgid=<123.foo@bar>
imap(user): deleted: uid=908, msgid=<123.foo@bar>
imap(user): expunged: uid=908, msgid=<123.foo@bar>

You can enable the plugin by setting:

mail_plugins = $mail_plugins mail_log notify
