[Dovecot] mail_max_userip_connections

[Richard Stockton]

What is the appropriate setting for mail_max_userip_connections ?

My POP3 connections seem to be mostly 1 at a time, but my IMAP
connections are often 3 per user per IP.  Is this appropriate?
If I change the IMAP setting to mail_max_userip_connections=1
will it break things for the user?

I am trying to improve this situation:
 > ps auxwww | grep "imap " | wc
     237    3080   22400

TIA,
  - Richard
