RE: [exim] how to stop exim from reverse lookup check for tr…

Khalid

Try replacing everything in your ACL section with the contents of the
attached file, and see whether it makes any difference.

You can test it yourself by going into SSH and typing

exim -bhc 70.156.1.178
EHLO FALCON
MAIL FROM: user@???
RCPT TO: localuser@???
DATA
Whatever
.
QUIT
