The authentication is part of the SMTP command stream so I don't think the 
Cisco can do it for you.

I don't use iSeries SMTP so I can't tell you if authentication is 
supported.  Hopefully someone else can give you a definitive answer.

If the iSeries cannot do the authentication, two options come to mind:

1. Set up a small server to run MTA software which CAN do the 
authentication.  Use this server for all of your mail processing.  The only 
mail processing that the iSeries would do is sending mail, relaying it via 
that server.  If you go this route, I'd recommend a Linux-based server.

2. Relay through some ISP other than Verizon, who will authenticate just on 
the basis of your static IP address.

Considering the number of people who are blocking Verizon's mail servers at 
their router because of Verizon's brain-dead and totally abusive method of 
"validating" incoming email, I'd recommend option 2.  If you go that route, 
be sure to use a white-hat ISP so that you aren't going from the frying pan 
to the fire.
