Hi
I have an exim front end server and an exchange backend server. All seems
fine except that I can't send emails to users on 123-reg's server. all
messages come back as:
gordonmckee@???
SMTP error from remote mail server after RCPT
TO:<gordonmckee@???>:
host mx0.123-reg.co.uk [195.224.48.120]: 550-Verification failed for
<gordonmckee@???>
550 Sender verify failed
I have tried to see if callforward is working and AFAIK it is based on the
info below. If I telnet to the box and tap in two valid addressed it work
(see below) and if I tap in an invalid address (see further below) it fails
as it should do!!

Does anyone have any ideas why I can't send mail to

send mail to!!)
Many thanks
Gordon
