What's interesting is that this is happening on a mail server that has
a: .ca TLD. It _looks_ like SA is appending this TLD to: localhost,
queries for it and it fails and then it queries correctly for:
localhost, which succeeds.
And what does "ping localhost" (running with the same user as SA) say?
I'd guess it might have the same behaviour, in which case it is not
SA-related...
I'd like this spurious lookup for: localhost.ca to stop ... has anyone
seen something similar - either: localhost.ca or: localhost.tld for a
mail server with another TLD (ie: mail.com -> localhost.com) ?
If others have seen this, is it result of a configuration parameter ?
I've seen it in the past with misconfigured /etc/hosts (missing
localhost entry) so search (or domain) from /etc/resolv.conf was
being used as it would be for any unqualied host name...
(it also might be a permission problem on those files, or
chroot / SElinux / Apparmor, or /etc/nsswitch.conf etc)
Hi Matija,
Thank you for your quick reply. You were absolutely right - this was an
issue with my: /etc/resolv.conf and _not_ SA.
Everything looks like it's working correctly and the: localhost.ca
lookup is no longer happening.
