[Dovecot] feature request: login in process title

[Marten Lehmann]

Hello,

I'm a bit afraid of users, the might slow down the server because of 
search requests to the imap-server on very large mailboxes. Even with a 
performant index, this could cause a lot of cpu and i/o-load. Is it 
possible to include the login-name in the imap process, so that a "ps 
ax" doesn't just give "imap", but e.g. "imap test at example.com"? Maybe 
it's of general interest to see in the title at which stage an 
imap-process is working.

Regards
Marten
