problem with sendmail on obsd. .com.au turned into com.au.com.au
I've recently had a strange (for me) sendmail problem on various obsd boxes. The config for these different boxes hasn't changed in ages, but for some reason, sendmail on them all started up play up all at about the same time. Instead of relaying email to localhost as shown below: Jul 22 20:00:04 int-firewall sm-mta[18685]: k6MA01XY018685: from=[EMAIL PROTECTED] all.sbisolutions.com.au, size=4919, class=0, nrcpts=1, msgid=200607221000.k6MA [EMAIL PROTECTED], proto=ESMTP, daemon=MTA, relay=smm [EMAIL PROTECTED] [127.0.0.1] It started doing the following: Jul 23 00:00:09 int-firewall sm-mta[29790]: k6ME010O004304: to=[EMAIL PROTECTED] l.sbisolutions.com.au, delay=00:00:03, xdelay=00:00:03, mailer=esmtp, pri=32018 , relay=int-firewall.sbiso...ons.com.au.com.au. [204.13.161.23], dsn=4.0.0, stat =Deferred: Connection refused by int-firewall.sbisolutions.com.au.com.au. Note the .com.au.com.au at the end which obviously doesn't exist. My configuration is unchanged and has been working for months. I don't have .com.au.com.au listed in any of my config files. Mail then just started queueing up in /var/spool/mqueue What ever I've done wrong, I've done wrong in a consistent way as about 5 of my other obsd boxes (both 3.8-stable 3.9-stable) in other locations all did a similar thing at the same time. I couldn't figure out what I did wrong, so just to get things working again, it tried adding in an entry to /etc/hosts pointing int-firewall.sbisolutions.com.au.com.au to 127.0.0.1 This didn't work as I guess sendmail doesn't use /etc/hosts. Finally, I added a the domain .com.au.com.au to named, and added in an entry for int-firewall.sbi to 127.0.0.1 This horrible hack got things working, but obviously I would like to find out what went wrong. Any idea's Thanks, Craig.

I'd rather suspect soem DNS screw up, check whether the intended name resolves on this box. (check twice ;-), check the bind instance which should be queried by sendmail and check the name servers configured in resolv.conf. sometimes this is not the same) I couldn't figure out what I did wrong, so just to get things working again, it tried adding in an entry to /etc/hosts pointing int-firewall.sbisolutions.com.au.com.au to 127.0.0.1 This didn't work as I guess sendmail doesn't use /etc/hosts. I _think_ this depends on your resolv.conf --knitti

I don't have .com.au.com.au listed in any of my config files. Mail then just started queueing up in /var/spool/mqueue As already noted, this is almost certianly a name resolution problem. Since it started affecting several machines around the same time you've either changed resolv.conf/hosts on all those machines (unlikely, as I'm sure this would have occured to you), or something is wacky with your DNS server(s). Missing a . at the end of a PTR record causes fun problems, and it's hard to spot. That's exactly the kind of thing you should look for, though. -- Darrin Chandler| Phoenix BSD Users Group [EMAIL PROTECTED] | http://bsd.phoenix.az.us/ http://www.stilyagin.com/ |
