Here is my problem.
I am trying to forward the mailbox on the exchange server to an offsite
sales rep at their ISP mail. I have set up the custom receipent with the
external address and the exchange mailbox delivery options to forward to the
offsite mailbox. When I send a message from another exchange server mailbox
to the sales rep it gets forwarded to him offsite. But if I try to send him
a message from my yahoo account i get it kicked back. System Admin message
saying there was a restriction that prevented delivery. I cannot find the
restriction anywhere in exchange server.
If you know what I should do please let me know.
