Address extension and 550-Mailbox unknown
in [Postfix]
|
From: Joachim Rosskopf on 5 Sep 2007 07:53 Hello, I have common setup with postfix-2.2.9-10, amavisd-new-2.3.3-17 and cyrus-imapd-2.2.12-27 running quite well. But currently traffic increases and some issues with my setup makes me run into some trouble: I currently use the address-extension: @addr_extension_virus_maps = ('Virus'); @addr_extension_spam_maps = ('Junk'); @addr_extension_banned_maps = ('Banned'); @addr_extension_bad_header_maps = ('Badh'); $recipient_delimiter = '+'; $final_virus_destiny = D_DISCARD; $final_spam_destiny = D_PASS; to have spam mails filed into the Junk folder in the users inbox. That works quite well for well configured mailaccounts. But there is a problem in case the user deletes the mailbox or it simply doesn´t exist (e.g. a public folder). Postfix says then: ..... to=<+public.webmaster+J...(a)my.hostname>, relay=/var/lib/imap/ socket/lmtp[/var/lib/imap/socket/lmtp], delay=0, status=bounced (host / var/lib/imap/socket/lmtp[/var/lib/imap/socket/lmtp] said: 550-Mailbox unknown. Either there is no mailbox associated with this 550-name or you do not have authorization to see it. 550 5.1.1 User unknown (in reply to RCPT TO command)) And tries to bounce that mail back to the possible spam sender. As the host is probably inexistent the mail gets stuck in the mail queue. Is there a way to discard the spam mail, if there is no Junk folder? Suggestions anyone? Regards. --- Joachim

From: Joachim Rosskopf on 5 Sep 2007 10:44 Hello, thank you for the fast reply. But I´don´t know exactly what you mean. How should I configure cyrus to accept as well, if the mailbox is not existent and if I can´t guarantee that the desired mailbox exists. I thought more or less of a configuration rule, that says postfix to drop ( or as an alternative and more secure way catch all to a single account ) mails routed back from amavis, if user does not exist. But if a solution through cyrus imapd is more elegant, give me a clue!
