Rejecting unknown/misconfigured mailclients
by Tobias Glasow 21 Mar '05

21 Mar '05

Hi all, Can some of you tell, how you deal with mailservers sending mail to your servers, which have not/incorrect configured dns informations? Postfix rejects mail with "reject_unknown_client", even when a ptr record exist, but forward and reverse lookup are not identical. In our logs we see this misconfiguration happen very often. When I activate blocking these clients, the reject rate nearly doubles. Just want to know, how you deal with this. Do you reject mail from clients with misconfigured dns or do you tolerate it? Regards and have a nice weekend.

Sendmail patch for non RFC conform DNS answers from bluewin
by Martin Blapp 18 Mar '05

18 Mar '05

Hi all, The recent bluewin migration to new dns load-balancers broke sendmail on BSD systems. It seems that the BSD resolver (not relevant if one uses bind8 or bind9) is different than the one in linux. I suspect that all BSD systems have this problem, including MacOSX. The following sendmail patch does work around this problem. It is not 100% correct but does work for now. --- sendmail/daemon.c.orig Thu Mar 17 10:15:11 2005 +++ sendmail/daemon.c Thu Mar 17 10:12:34 2005 @@ -2256,7 +2256,7 @@ /* check for name server timeouts */ # if NETINET6 if (WorkAroundBrokenAAAA && family == AF_INET6 && - errno == ETIMEDOUT) + (errno == ETIMEDOUT || h_errno == TRY_AGAIN)) { and of course you'll need this option in your MC File: define(`confBIND_OPTS', `WorkAroundBrokenAAAA')dnl Martin Martin Blapp, <mb(a)imp.ch> <mbr(a)FreeBSD.org> ------------------------------------------------------------------ ImproWare AG, UNIXSP & ISP, Zurlindenstrasse 29, 4133 Pratteln, CH Phone: +41 61 826 93 00 Fax: +41 61 826 93 01 PGP: <finger -l mbr(a)freebsd.org> PGP Fingerprint: B434 53FC C87C FE7B 0A18 B84C 8686 EF22 D300 551E ------------------------------------------------------------------

Bluewin Server auf SpamCOP und Spamhaus

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Sehr geehrte Damen und Herren, Wer kann mir bei Bluewin helfe, dass sie von der SpamCop und Spamhaus Liste kommen ? Bluewin Kunden werden vom Bluewin Support falsch Informiert oder angelogen, das Bluewin keine Probleme hat mit Spam und das in unserem Fall Genotec der übeltäter ist. Wenn aber ein Mail solche Informationen enthalten sollte der Bluewin Support etwas besser Informieren können vorallem wenn das seid einer Woche der Fall ist siehe SwiNOG Post. SpamCop Remote MTA smtp.genotec.ch: SMTP diagnostic: 554 Service unavailable; [195.186.18.61] blocked using bl.spamcop.net, reason: Blocked - see http://www.spamcop.net/bl.shtml?195.186.18.61 Remote MTA smtp.genotec.ch: SMTP diagnostic: 554 Service unavailable; [195.186.18.62] blocked using bl.spamcop.net, reason: Blocked - see http://www.spamcop.net/bl.shtml?195.186.18.62 Remote MTA smtp.genotec.ch: SMTP diagnostic: 554 Service unavailable; [195.186.18.63] blocked using bl.spamcop.net, reason: Blocked - see http://www.spamcop.net/bl.shtml?195.186.18.63 Remote MTA smtp.genotec.ch: SMTP diagnostic: 554 Service unavailable; [195.186.18.64] blocked using bl.spamcop.net, reason: Blocked - see http://www.spamcop.net/bl.shtml?195.186.18.64 Remote MTA smtp.genotec.ch: SMTP diagnostic: 554 Service unavailable; [195.186.18.65] blocked using bl.spamcop.net, reason: Blocked - see http://www.spamcop.net/bl.shtml?195.186.18.65 Remote MTA smtp.genotec.ch: SMTP diagnostic: 554 Service unavailable; [195.186.18.66] blocked using bl.spamcop.net, reason: Blocked - see http://www.spamcop.net/bl.shtml?195.186.18.66 Spamhaus Remote MTA smtp.genotec.ch: SMTP diagnostic: 554 Service unavailable; [195.186.18.64] blocked using sbl.spamhaus.org, reason: http://www.spamhaus.org/SBL/sbl.lasso?query=SBL23877 Anwort die ein User von uns durch ihren Bluewin Support erhalten hat. Hier die Antwort von Bluewin zur Infformation: +++++++++ Lösung: Die Meldung "We do not relay" oder "Serverfehler 554" erscheint, wenn Sie den Bluewin-Mailserver als Relay (Transit) benützen, d.h., Sie haben sich nicht über Bluewin eingewählt. Die SMTP-Maileinstellung (ausgehender Mailserver) lautet aber auf "mail.bluewin.ch" und Sie senden Mails an eine Nicht-Bluewin-Adresse (xxxx(a)yyyy.zz statt xxxx(a)bluewin.ch). Dieses Vorgehen wird "Relaying" genannt und wird von Bluewin nicht unterstützt. (Dies nicht zuletzt aus dem Grund, dass wir unsere Kunden vor unerwünschten Massenmails oder "Spam" schützen möchten.) Um E-Mails versenden zu können, muss die SMTP-Maileinstellung dem jeweiligen Provider angepasst werden, d.h. Sie müssen den Postausgangsserver Ihres Providers eintragen. ++++++++++ Mit freundlichen Grüssen Marcel Stutz Netzwerk & Unix Administrator - ------------------------------------------------------------------ | Genotec Internet Consulting AG | E-Mail : marcel.stutz(a)genotec.ch Hegenheimermattweg 119a | Website : http://www.genotec.ch CH - 4123 Allschwil | -------------------------------- Schweiz | | Zentrale: +41 61 487 99 99 - ------------------------------- | Fax : +41 61 487 99 98 | Support : 0848 321 123 easy[hosting] | 500 MB, unl.Pointings, | -------------------------------- Subdomains und E-mails, | Supportanfragen bitte immer an Internetzugang und mehr | support(a)genotec.ch SFr. 150/Jahr | Web: http://support.genotec.ch | - ------------------------------------------------------------------ -----BEGIN PGP SIGNATURE----- Version: PGP 8.1 iQA/AwUBQhQ/WG67Rst+AWkCEQJL6QCcDDSPqOSKBzp9SXlUhdhnAIOJMBIAoL/I DsjWLARpwRufbVAvFwUT09IE =AJDa -----END PGP SIGNATURE-----
