[MlMt] can send mail but new mail doesn't download into inbox

[Ken Pope]

Thanks so much!  I've shut off the other mail clients until this 
problem can be solved.

As you suggested, I used the "take account online" function, which 
turned the source account back from red to black, and all the folders 
underneath back to black from gray. (Thanks, again!)

However, though I can still send, the inbox does not download incoming 
mail.  

And as the source account was trying to refresh, the following message 
popped up:

[begin pop-up]

IMAP problem for "ken at kenpope.com" account
MailMate encountered the following error: "Warning: Non-standard 
response treated like NO (response: "Disconnected for inactivity.", 
command: "").".
Mailbox: "INBOX/Sent".

Retry   Take Account Offline   Try Later

[end pop-up]

Any further steps I could take to solve the problem?

Ken
