When I couldn't find all these names _exactly_ I went back to the books
(and manuals). I'm waiting to test my settings but I wanted to share
what I did and as soon as it is tested I'll let the list know what it
actually took to do this.
FYI, I used Kyle Dent's Book "Postfix: The Definitive Guide" ( I have a
Safari Account ) and did the following -- though this is the cleaned up
version. :-)
1. Create a file "helo_access.map" with the IP I trust and an ok
192.168.3.111 ok
2. postmap helo_access.map
3. Edit main.cf and added:
smtpd_helo_restrictions =
check_helo_access hash:/etc/postfix/helo_access.map
reject_invalid_hostname
4. postfix reload
Mail still appears to be flowing OK so I have to get a hold of the bank
now and get them to send some test messages or camp out on the log file
and wait to see what happens on it's own.
Thanks to Len for the quick response.
Rod
