[Dovecot] dovecot weird bug

Sun May 10 22:58:35 EEST 2009

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
