[Dovecot] Empty/corrupt mail leads to duplicate delivery
Hi,
when the attached mail was stored in a maildir, fetching mail via POP3 lead to multiple delivery of mails in that maildir to the client (Outlook). I replaced the domain with dots.
This is the dovecot configuration:
--snip-- protocols = imap imaps pop3 pop3s listen = * disable_plaintext_auth = no ssl_cert_file = /etc/ssl/dovecot/server.pem ssl_key_file = /etc/ssl/dovecot/server.key mail_location = maildir:~/.maildir
protocol pop3 { pop3_uidl_format = %08Xu%08Xv }
auth default { mechanisms = plain
passdb pam { args = "*" }
userdb passwd { }
user = root
socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } --snip--
Version: dovecot-1.1.4-r1 (Gentoo)
Gentoo applies the attached "expire" patch.
I tried to reproduce the behavior, but when I send an empty mail via telnet, nothing happens.
The box is running Amavis, don't know if that helps.

Sounds like an Outlook bug. The only thing Dovecot could do wrong is to provide duplicate UIDL for the messages. You could verify this yourself by giving UIDL command and seeing if there are duplicates. But I highly doubt that, because you're using:
pop3_uidl_format = %08Xu%08Xv
Which means your UIDL is based on message UID and UIDVALIDITY. Neither depend on message contents.
