Hi everybody,

I have a little problem, when i am trying to read an email
via imap my thunderbird is trying (for ever) to read it.

My dovecot tells me :

dovecot: Apr 29 22:47:23 Error: IMAP(ebalaskas): FETCH for mailbox

It's seems that the for the specific mail the dovecot tries to reconnect
for EVER.

But why ?

Why i cant read this specific mail ?

i have more than 72.000 but in some messages i get problems
like that. And there are not corrupted
(the messages, it's an oreilly newsletter mail for god shake :p ).

Any ideas ?

i think this is relative to Authentication Cache options.
