After setting up chroot jail, I noticed a problem with my mail inbound and
outbound for sub-domains. I have multiple domains on my server, some with
sub-domians. The primary domain mail traffic is not effected by this latest
problem, just the sub-domains.
The system is runing RH 7.1. Users of the sub-domains access their mail via
Squirrel mail.
Here's an example of one of my DNS zone entries:
$TTL 3D
@ IN SOA ns1.manitobamall.net.
root.manitobamall.net. (
12 ; Serial
1H ; Refresh
2H ; Retry
4W ; Expire
1D) ; Minimum TTL
;
NS ns1
MX 10 mail;
;
A 206.45.64.137
ns1 A 206.45.64.137
www A 206.45.64.137
mail A 206.45.64.137
winnipeg A 206.45.64.137
www.winnipeg A 206.45.64.137
me2u.winnipeg A 206.45.64.137
www.me2u.winnipeg A 206.45.64.137
maac A 206.45.64.137
www.maac A 206.45.64.137
mpa A 206.45.64.137
www.mpa A 206.45.64.137
The sub-domains are reflected in /etc/mail/local-host-names.
Attempting to send mail to a sub-domain results in this showing on my server

<rhenry at maac.manitobamall.net>
2 b host map: lookup (maac.manitobamall.net): deferred
So, the mail appears to be be arriving at my server, and then being
"deferred". Attempts to force the queue (/usr/lib/sendmail -v -q) result in:
Running /var/spool/mqueue/g9ELg9X01184 (sequence 1 of 4)
<rhenry at maac.manitobamall.net>... maac.manitobamall.net: Name server timeout
<rhenry at maac.manitobamall.net>... Transient parse error -- message queued
for future delivery
Last time I *know* that mail for the sub-domains was working was last
weekend, so this has just come up since then. No changes have been made to
sendmail or DNS entries. The only changes on the server was to set up the
chroot jail stuff, and I can't see how that would effect this...
What am I missing?????
