Hi everyone,
I'm trying to find a solution for this bug who appears 2 months ago :
dovecot: imap(%USER%): Error: read(<binary stream of mailbox INBOX UID
(%d)>) failed: Broken pipe (FETCH BINARY[2] for mailbox INBOX UID (%d)
Where %USER% is the unix user and %d the UID of the mailbox.
This error appears each time a user tries to download an attachment from
one of his emails. Whether with RoundCube or Thunderbird via VPN or not.
I thought that it was related to my firewall but no. Furthermore the
problem isn't present when users are at the office. Upload speed from
our ADSL connection is pretty slow about 1mpbs, I thought maybe it was
related but it was working fine since 2 years. So I'm really short of
ideas.
Anyone could help me please ?
Best regards,
Carl

This does turn the pointing finger towards firewall (despite what you said). Can you take pcaps from this, since it seems to be reproducible and send them to me privately? Aki
