I have a customer who is forwarding email from an internal account to her blackberry via her blackberry email address. I have setp an acc as per normal with her blackberry details in and set her main acc to send a copy to this one for sending out.
Now when someone sends her an email she recieves it on both work PC and blackberry, however sender then recieves an email back saying it could not reach her acc for external mail
i.e the following recipents cannot be reached
Joe Bloggs (external) there was a problem with your SMTP etc etc etc contact system admin ( joebloggs.com)
SMTP 550 (firstname.lastname@example.org).......
I could understand the issue if she simply wasn't getting email on her blackberry but I'm also suprised that an internal forward would generate a message that would get back to the sender anyway, sureley it would just log it....
Any help would be great
