Hi all Using the POP3 server of Cyrus IMAP Server 2.3.13 I can see the following POP3 protocol (sniffed via tcpdump and friends and obfuscated sensitive data): ---------------------------------------------------- +OK <98640940.1241005202@xxxxxxxxxxxxxxxx> imap.example.com Cyrus POP3 v2.3.13-Gentoo server ready USER username +OK Name is a valid mailbox PASS passphrase +OK Mailbox locked and ready UIDL +OK unique-id listing follows 1 1157352258.220081 2 1157352258.220082 . LIST +OK scan listing follows 1 14363 2 360389 . RETR 1 +OK Message follows Return-Path: <sender@xxxxxxxxxxx> Received: ... /// here the email headers and body follow RETR 2 DELE 1 DELE 2 QUIT ---------------------------------------------------- The point I am interested in is the fact, that both the UIDL and the LIST commands show TWO mails. But when the client tries to retrieve the second one (RETR 2), nothing is returned. This does not happen all the times - I've already seen non-empty "RETR 2" calls during other client sessions. Is this normal behaviour? Or do I have to afraid of mail loss, because after the empty "RETR 2" the clients deletes BOTH messages from the server. Is this strange message 2 really "not-existing", or do I loose some mail data anywhere? Thanks and regards -stefan- ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
