[aklug] Re: Postconf review

This may bite you:
mkm@mx1:/etc/MailScanner/reports/en$ host mail.tj49.com
mail.tj49.com has address 74.220.215.66

mkm@mx1:/etc/MailScanner/reports/en$ host 74.220.215.66
66.215.220.74.in-addr.arpa domain name pointer host266.hostmonster.com.

Your forward and reverse addresses don't match for your mail host. I
presume you'll be sending through this host as well as receiving from it.
