[BlueOnyx:13069] Re: find unused e-mail users

[Eric Peabody]

Stuart,

This will list the inbox files by date:

     ls -lt /home/sites/*/users/*/mbox

Certainly users who have not gotten mail recently are ones to consider 
removing.  However any spam delivery would affect that. Also try listing 
the mail directories by modification time.

     ls -ltd /home/sites/*/users/*/mail

It would be nice to have reports of login activity but that is not part 
of the package.  In the absence of a login report, listing users who 
have not sent or received mail is a reasonable proxy. Still, I would 
generate a candidate list from the commands above and then grep the mail 
logs, as in:

   zgrep <user> /var/log/maillog*|grep dovecot

(Replace <user> with the user name of interest.)

Since password guessing might affect this, you might check the IP 
address with, "whois <IP>" and make sure it is a reasonable address.

Finally, check the .forward file of any user you consider deleting.  A 
user may have all their mail forwarded elsewhere and so not show up in 
any of the above.

Eric
