my Zoho mail account has been blcoked for IMAP use for several days now. When I try to connect with Thunderbird 6 I get an error message:

"Your account is temporarily blocked for IMAP use. This may happen when you exceed the maximum number of simultaneous IMAP connections..."

I only use Thunderbird at two computers and K9 Mail on my Android phone. Could you please unblock my account as soons as possible and explain how to avoid the problem in the future.

Cheers,

Tristan
