Some providers, including Google, use rate-limiting on their servers.
This can affect IMAP service, especially if Evo is set to use multiple
simultaneous connections. You can limit this in Edit->Preferences-><account>->Receiving Options->Number of 
concurrent connections to use. I 
have it set to 2 for Gmail, but
YMMV.

Aside from that, make sure you've ticked "check for new messages in
subscribed folders".
