[Dovecot] Probleme decoding attachements with Apple mail client

Hello folks

An Apple user here have troubles between Dovecot and its Apple mail client that presents ALL attachements inline inside emails instead of "Attachements" the problem occurs only when using IMAP , when using POP3 attachements appears as they are supposed to do.

I would like to know if other Apple users in this list has experienced and solved that problem , the machine in running MacOS 10.5

Thanks a lot.
