start configuration
I have two computers. Our e-mail server is comcast. Computer-1 has e-mail #1; computer-2 has e-mail #2. Computer-2 forwards certain e-mails to computer-1, and vice-versa. Recently I upgraded computer-2 to computer-3. Everything went smoothly, EXCEPT Computer-3 cannot forward e-mails to computer-1 (computer-1 can forward to computer-3). I get the following error message:
"Sending of the message failed. An error occurred while sending mail. The mail server responded: Not our Customer. Please check the message recipient " [edited] @comcast.net" and try again."
What gives?

That error suggests the address you are forwarding to is not correct as server says it does not exist. 550 Not our Customer. This error results when a message is sent to a non-existent Comcast customer. http://postmaster.comcast.net/mail-error-codes.html
As you have filters doing the 'forwarding'. Check the Message Filter to see if there is a spelling mistake in the forwarding to comcast address. This could be a small error like a space in the wrong place, a comma where there should be a full stop.
I presume this only occurs on the filtered forwarded email and you can otherwise send emails perfectly ok.
