What about talking POP3 protocol directly? telnet pop3.server.org 110 user foo pass bar uidl retr 1 retr 2 retr 3 quit Does that work? (Try from the client machine first, and if that doesn't work try again from localhost.) > Can anyone confirm this? Is dovecot for some reason unable to deliver > such identical mails? No. But what do you have in pop3_uidl_format? If POP3 UIDLs differ, I think it's unlikely the problem is with Dovecot itself (but instead with some anti-virus/firewall/whatever in the middle).
