[rancid] Weird email problem

[Lai Chen Kang]

Hi all

I have intentionally made modification to one of my switches. I want 
rancid to generate a mail and sent it to me. Below is a snippet from 
/var/log/maillog

Jan 17 12:00:21 STMGSINMANAGE2 sendmail[8428]: m0H40LbF008428: 
from=rancid, size=5978, class=-60, nrcpts=1, 
msgid=<200801170400.m0H40LbF008428 at STMGSINMANAGE2.transmarket.com.sg>, 
relay=rancid at localhost

Jan 17 12:00:21 STMGSINMANAGE2 sendmail[8430]: m0H40L55008430: 
from=<rancid at STMGSINMANAGE2.transmarket.com.sg>, size=6286, class=-60, 
nrcpts=1, 
msgid=<200801170400.m0H40LbF008428 at STMGSINMANAGE2.transmarket.com.sg>, 
proto=ESMTP, daemon=MTA, relay=STMGSINMANAGE2.transmarket.com.sg [127.0.0.1]

Jan 17 12:00:21 STMGSINMANAGE2 sendmail[8428]: m0H40LbF008428: 
to=rancid-switches at transmarket.com.sg, ctladdr=rancid (500/500), 
delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=143978, 
relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (m0H40L55008430

stat=Sent

/etc/aliases

rancid-admin-firewalls: laichenkang at transmarket.com.sg
rancid-firewalls:       laichenkang at transmarket.com.sg

Problem is I never got the mail. Even when the last line is stat=Sent.

Any ideas?
