[rt-users] Problems to send mail

[Darvin Denmian]

good afternoon,

first of all, sorry by my bad english.... :(

i'll try to explain my problem here:

- I have one queue with the following reply address : user at example.com
- My domain is : @foo.bar

When RT try to send a mail message to user at example.com  i get the
following error:

<user at example.com>: host smtp.example.com[XXX.XXX.XXX.96] said: 554 5.7.1
<user at example.com>: Relay access denied (in reply to RCPT TO command)

My Question:
Rt don't work with more than one domain?
How can i fix this error?
