Hi,

Hopefully this is a simple problem but searching google has not found a
good solution.

Mail sent from FC6 system is not being delivered. It was working fine
and then stopped 5 days ago.

Running mailq I see the mail messages in the queue. E.g.:
l0JCRCxq014675 7623 Fri Jan 19 05:31 MAILER-DAEMON
(host map: lookup (adomain.ca): deferred)
charles@adomain.ca
If I run '/usr/sbin/sendmail -v -q Il0' it delivers all the messages
just fine.

Pinging adomain.ca and doing an nslookup on it resolves the domain just
fine.

Here is the output from 'sendmail -d0.1':
Version 8.13.8
Compiled with: DNSMAP HESIOD HES_GETMAILHOST LDAPMAP LOG MAP_REGEX
MATCHGECOS MILTER MIME7TO8 MIME8TO7 NAMED_BIND NETINET
NETINET6
NETUNIX NEWDB NIS PIPELINING SASLv2 SCANF SOCKETMAP
STARTTLS
TCPWRAPPERS USERDB USE_LDAP_INIT

============ SYSTEM IDENTITY (after readcf) ============
(short domain name) $w = localhost
(canonical domain name) $j = localhost.localdomain
(subdomain name) $m = localdomain
(node name) $k = bloomsbury


Any ideas what the problem could be?

Have you tried restarting the daemon? As with any long-running daemon
(due to the implementation of the resolver library), the sendmail daemon
doesn't pick up changes to /etc/resolv.conf automatically - what you
describe would be consistent with decomissioning the name server(s)
(addresses) given in /etc/resolv.conf and putting new ones in there.

Thank you Per. That was it. Although, I didn't make any changes to
/etc/resolv.conf. Perhaps it was a dependent library update.
