Re: AS400 SMTP relay blocking at V5R1 not working

[Neil Palmer <neilp@xxxxxxxxxxx>]

Use OpsNav (Servers, TCPIP, SMTP, Properties, Relay Restrictions) and 
check the settings.  I found migrating to V5 that it did correctly move 
the entries over from the QTMSADRLST file to the Address Relay List when 
the V4 to V5 upgrade was run, BUT the button that tells it to "Accept 
relay messages from only the address relay list"  does NOT get checked ! I 
complained to IBM about this - I suggest everyone who upgrades to V5 and 
finds the same problem also complain.

Note also the other SMTP properties, Connection Restrictions, Filters.

Is jims.com in the host file on your AS/400, or is the domain setup so it 
looks like the
AS/400 handles mail for jims.com?  Also make sure you understand 
"relaying" and "Reject
connections from"  relaying means I will accept email for a domain that I 
do not
handle/backup email for, (NO MX records or an A record if no MX records at 
all) and figure
out what to do with it. Reject connection from means I do not care who you 
are trying to
send email to, I am not going to take anything from you (Blacklisted).
