I just moved from FC2 to FC3 and I think I have my mail sendmail config
just as it was for FC2. Sendmail receives mail for local delivery just fine, but outgoing mail does not send.
I use my ISPs SMTP server as a smart host. In sendmail.mc:
define(`SMART_HOST',`relay.plus.net')
'mailq' shows a bunch of mail not being sent due to host name lookup failures:
iACC9XnN003813* 6874 Fri Nov 12 12:14 MAILER-DAEMON
(Deferred: Name server: relay.plus.net: host name lookup fail)
<accounts@xxxxxxxxxxxxxxxx>
iACB9XVo003702 8287 Fri Nov 12 11:12 MAILER-DAEMON
(Deferred: Name server: relay.plus.net: host name lookup fail)
<gemm.com-at-eliotstock.com@xxxxxxxxxx
If I run sendmail in test mode to test the name lookups, I get this:
[root home ~]# echo '/mx relay.plus.net.' | sendmail -bt -d8.8 ADDRESS TEST MODE (ruleset 3 NOT automatically invoked) Enter <ruleset> <address>
getmxrr(relay.plus.net., droplocalhost=0)
getmxrr: res_search(relay.plus.net.) failed (errno=110, h_errno=2) getmxrr(relay.plus.net.) returns -1 value(s):
[root home ~]# echo '/map host relay.plus.net.' | sendmail -bt -d8.8 ADDRESS TEST MODE (ruleset 3 NOT automatically invoked) Enter <ruleset> <address>
map_lookup: host (relay.plus.net.) dns_getcanonname(relay.plus.net.,
trymx=1) dns_getcanonname: trying relay.plus.net. (AAAA) NO: errno=110, h_errno=2 dns_getcanonname: trying relay.plus.net. (A) YES dns_getcanonname: relay.plus.net returns relay.plus.net. (0)
And indeed I can ping relay.plus.net ok, but it has no MX record - not sure if that's the problem. Does sendmail need to lookup an MX record for the smart host before it sends? This worked on FC2 I think, and my ISP's DNS records haven't changed.
Cheers,
