I'm using FogBugz to pull support queries from a GMail inbox, so I have the option of using either POP or IMAP.
I find that FogBugz can take a few minutes to pull new cases from the email account using IMAP.
If I want my queries to be indexed by FogBugz as quickly as possible, is there any preference for POP over IMAP?
And if I leave messages on the server, will IMAP checking slow down over time?
