-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hello list
I currently have a weird problem with my postfix installation. Emails to the domain ogrj.ch cannot be sent anymore. Postfix claims that no MX host for said domain has a valid address record. A dns query for the MX of this domain tells me that the following hosts act as MX ogrj.ch. 3057 IN MX 10 smtasg01.abxsec.com. ogrj.ch. 3057 IN MX 20 smtazh01.abxsec.com. ogrj.ch. 3057 IN MX 110 smta2.abxsec.com. ogrj.ch. 3057 IN MX 120 smtp1.seabix.com. ogrj.ch. 3057 IN MX 130 smta4.abxsec.com. ogrj.ch. 3057 IN MX 140 smta3.abxsec.com. ogrj.ch. 3057 IN MX 510 mtas.abxsec.com. ogrj.ch. 3057 IN MX 520 mtaz.abxsec.com. In the postfix logs I get the following: Jun 11 11:09:07 smtp2 postfix/smtp[19862]: warning: no MX host for ogrj.ch has a valid address record Jun 11 11:09:07 smtp2 postfix/smtp[19862]: 2B25317FA69: to=<removed_for_priv...@ogrj.ch>, relay=none, delay=0.18, delays=0.15/0/0.03/0, dsn=5.4.4, status=bounced (Host or domain name not found. Name service error for name=smtp1.seabix.com type=A: Host not found) what I do not understand so far is, that postfix seems to try to connect to smtp1.seabix.com which has prio 120 Why does postfix not try to connect to the 10 or 20 prio hosts? For other domains which are handled via the same MX we could deliver without any problem to MX host with prio 10 Jun 11 11:28:23 smtp1 postfix/smtp[6995]: 8127A17F87B: to=<removed_for_priv...@stadt.sg.ch>, relay=smtasg01.abxsec.com[193.246.80.88]:25, delay=1.4, delays=0.04/0/0.12/1.3, dsn=2.0.0, status=sent (250 2.0.0 t5B9SMtO014723 Message accepted for delivery) The difference between these two domains is that stadt.sg.ch only has two MX hosts stadt.sg.ch. 60 IN MX 20 smtazh01.abxsec.com. stadt.sg.ch. 60 IN MX 10 smtasg01.abxsec.com. Does anyone have a clue where I could dig more to narrow the source of the problem? Thanks for any idea Cheers tobi -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJVeXn2AAoJEDUc5iWoaKTkFnEP/jjKrJRzSrcUDLsc1LKDtR+y vKSLAj6cc79HsOIIWQGmuUPFuTrFddes+ztnonzBINqAoGt3xfvkj8cTqYGmICkm h4C4sByip4lVhROndgT57fmxN0e5+mxAkhE8MAkC197cvkiaWCe9ziLcpxfMunju hRLEhKJxc3+Wt75/sI6mz4+/PBJtJ4ygAMXmOZ+jBR0eWTpHIdUSQ4aBKOBfVS12 6nFSggtV/UwTXXMo1wIqjU6BttL3FGGrjmAwUS5XXrd7q7TmtMoXnrfQgRP1KQGg +3WubcLlYiI2o/7L47QMw/KgFrhiOL4kwrGNn1WaPwwMQWAFlvCwD14fTMlU51i8 j7oYegAXAW6cgL4C8S33M5XquHNuUOhx2uUjtz5sBqjOEU/pYIRbYGS47AGfGmOM IUi+YCxZeWl6tN6l2jnzCiG+Q8L0agsdZHddYgNOPUsnxn8/npTdzk0fti+XgoSN sFeiYQW8w2B88vPVxEZbrKSjoQS9GKjRICqP2i8KmQhApAGapkZulLHNdF7R2bKs 5gsSN5dgCUvCe3cF/XDi7kabmuQDbAoUkhnp5kKMDvCav57fQ6kkVt1naP1zyN+e NcdUXsgYfsZD35PQeh8/OacC9uSe8rSM1qVjDi1OW8iHkitD7avvcEHabqY7AB7u bFJ8HhvatqMmi9J4fzBe =zmJX -----END PGP SIGNATURE-----
