It seems that I was wrong about the possible cause of this and the problem persists. Can someone using Dovecot 1 ( any beta release from 3 to 7 + LDA ) and Thunderbird 1.5 ( Linux or Windows ) confirm this problem. It comes up when forwarding a message as attachement to any user on the same dovecot server. When forwarding to any user outside or forwarding from another IMAP server, everything works as expected. The message appears to have an attachment in the Sent folder, but it completely blank in the inbox. Problem with LDA ?
Just switched from uw to dovecot ( latest beta3 + lda ) on production system and everything seems fine except... There's some strange problem with forwarding messages from thundebird, the body of the forwarded message is always completely blank - 0 byte size. Forwarding from squrrel, horde, eudora and outlook works fine. Client setup on thunderbird installs hasn't changed a bit. I'm still investigating why this is happening.
Has anyone run into this ?
