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 end: qfg9ELg9X01184 Mon, 14 Oct 2002 16:33:33 -0500 "Raymond J. Henry" rayhenry@mts.net rhenry@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@maac.manitobamall.net... maac.manitobamall.net: Name server timeout rhenry@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?????
