Checking Last time a user checked their mail? (Postfix)
 

Hello,

Im trying to figure out the last time a user had checked their email so I can weed out the inactive accounts.

I tried checking the /var/mail/*account* file on an account but wasnt able to see any sort of timestamp.

Im using postfix.

Any suggestions would be greatly appreciated ! :)

quick update:

I just used the following to grab all the logins in var/log/maillog , but not sure if this is correct or not

Depends a bit on how long you keeps your logs for.

Yeah sadly it seemed to be only about 7 days...so no luck :(

Track last user authentication (smtpd/submission)
 

Hi
Recently i made a daemon in python to track last user authentication when he send an email ( ports 465 and 587 ), ( see for yourselves https://github.com/noskoski/postfix_smtpd_last_auth/ ).
But if you want to track pop3/imap you may user post-login function from dovecot. https://wiki.dovecot.org/PostLoginScripting
