Is there anyway I can get Dovecot to update mtime on dovecot.index everytime a user successfully checks there email? Or perhaps there is a better way to do what I want here.I am working on a script that I want to check when the last time a user checked there email account. If a user has not checked it in say 6 months I want to automatically suspend the account through the MTA. If they start checking it again I also want to automatically reinstate it. What I thought was a good way was to look at the mtime on dovecot.index but a user can be checking there email daily but if they do not receive a new message in say 6 months the mtime will date back to 6 months still. Ran into this with an email address used by a fax machine. So is there a better way with dovecot to determine this? I am using dovecot-1.0.rc29 right now.
[From an email I wrote in October] You can do this (and many other things) through Post-Login Scripting: http://wiki.dovecot.org/PostLoginScripting See in particular “Last-login tracking”: http://wiki.dovecot.org/PostLoginScripting#line-20 [...and for your situation:]I think I'd avoid actually disabling the account through the MTA, especially if it's for security considerations and your accounts have shell access. But it wouldn't be that hard:
In dovecot.conf, set your IMAP login script as follows:
protocol imap {
# ...
mail_executable = /full/path/to/loginscript.sh
Then, use the attached loginscript.sh. (and chmod +x it)
Tested with 1.0.5 under Gentoo. The 'stat' and 'date' commands might need
alteration depending on your particular flavor of O/S.
(I also realized after writing it that you probably meant to disable mail delivery, not IMAP access. But, it was a fun exercise.)
In that case, all you need in loginscript.sh is: #!/bin/sh touch $HOME/.dovecot-lastlogin exec /usr/libexec/dovecot/imap Then run a cron job to disable delivery through your MTA of choice. Best, Ben
