Hi,

We have a weird bug happening in our dovecot installation. When I send html emails from many clients and compress them, there are no problem. They are opened and correctly formated.

When I send an email from Squirrelmail and compress it, dovecot exits with no errors (there are no coredumps or seg fault - dovecot just exits). But the weird is, it just happens when squirrelmail opens an email (compressed) that was sent by squirrelmail (all other clients can open it and squirrel can open all other emails sent by other clients). (Try with this message - compressing too - it occurs with me).

Best Regards, Fernando

Dovecot version: 1.2.rc3

Here is a copy of the message (uncompressed - opens / compressed - hangs).
