From: Wincent Colaiuta on 29 Mar 2008 16:45 I'm currently getting mailbombed with bounce messages because of the interaction between cyrus and sendmail (sendmail accepts spam message for unknown user, passes message to cyrus, cyrus rejects message, sendmail bounces back to non-existent address forged by spammer, remote mail server sends bounce message to the postmaster, me). I know this is a known issue and the question has come up quite a few times in the archives (search "smmapd" if you're curious), but a few years have passed since the last activity that I can find (2005), and I'd like to know if there is any way to avoid this problem _without_ hacking/patching Sendmail. This page outlines the steps that need to be taken, involving patching cf/m4/proto.m4: http://ftp.nakedape.cc/pub/anfi.homeunix.net/sendmail/rtcyrus2.html And the official cyrus site only says, "Cyrus also includes a socket map daemon smmapd ... To use this daemon, add smmapd as a service in cyrus.conf and configure Sendmail accordingly.": http://cyrusimap.web.cmu.edu/imapd/install-configure.html Basically, I'm wondering if in 2008 "configure Sendmail accordingly" can be down without patching. I'm running sendmail 8.13.8-2.el5 and cyrus 2.3.7-1.1.el5 (provided by Red Hat with RHEL 5.1). I didn't actually choose cyrus myself, it was just the "official" imap solution provided; things were a bit easier with UW-IMAP. Cheers, Wincent

One minor change tweak I made was to look up the domains in a flat file; ie: F{VCyrusDomains}/etc/mail/cyrus-virtual-domains Rather than: C{VCyrusDomains} example.net example.com That should be all right, shouldn't it?

It is another way of providing the list of cyrus virtual domains to RTCyrus - use whichever you like more :-) Feel free to report any problems (bugs) at http://sourceforge.net/tracker/?group_id=187085&atid=919883 *OR* positive results of the tests http://sourceforge.net/tracker/?group_id=187085&atid=995741 P.S. After small changes in cyrus imap it should be possible to make sendmail "know" that given cyrus mailbox is in "over quota" state before sending "RCPT TO" reply. -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)priv.onet.pl : anfi(a)xl.wp.pl Open-Sendmail: http://open-sendmail.sourceforge.net/ Men use thought only to justify their wrong doings, and speech only to conceal their thoughts. -- Voltaire |
