Weird behaviour


We are almost there…

I am running: RT3, Apache/modperl2, RH8, Postfix, exchange (as our mail

I can send emails through an SMTP connector and it will create a ticket.
I can then make comments on the ticket and CC someone on our exchange
domain… They will get the email. However, when I try to notify the
requestor (by making a comment and selecting the option from the pull
down), postfix says that it cannot relay the message… This is the same
user that I can send an email to if I put their address in the CC field.

Any ideas?
