COOL problem for email administrators

[aru510]

we have one mail server user id on that mail server is like
user@xxx.abc.org

know we want to chnage the user ids like user@abc.org
out setup is like

1 firewall
1 gateway(relay)
1 mail storage
1 dns

in dns there is MX enrtry for both xxx.abc.org and abc.org is pointed to gateway
know out user@xxx.abc.org is working but when u try to sendmail to user@abc.org then it shows error 550 : SMTP relay not allowed

on gateway there is setting that if mail for @abc.org then goto storage
and also if mail for @xxx.abc.org then go to storage
on storage the local domains are @abc.org, @xxx.abc.org

plz. tell what is the problem

You need to allow domain abc.org to be relayed:

the simplest approach is the first one. but read the all document.
