Is the contract signed?  If not, perhaps they should consider an
alternative - an external "routing" company that acts as an
intermediary and does spam and virus checking.  We use MailWatch
(www.mailwatch.com) and it is pretty good - it costs $200/month.

The simplest approach ... continue to use relaying - then no account
is needed.  Their administrators should be able to allow relaying for
specific IP addresses.
- get the IP address of the mail server for your account from 1&1
- have 1&1 allow relaying from the AS/400 address
- CHGSMTPA MAILROUTER (1&1 IP address) FIREWALL(*YES)
   --> This will force all outgoing mail to be routed to that server

If 1&1 is unwilling to allow relaying at all, then you will have to
instead have the SMTP server be a traditional mail server.
- CHGSMTPA MAILROUTER(*NONE) FIREWALL(*NO)
- make sure that the AS/400 has proper DNS server addresses
   --> CHGTCPDMN  INTNETADR(DNS server addresses)
   --> You may also want to add a route for MAIL.yourdomain.com to the
AS400 host table with CFGTCP, option 10
