Hi all



I have a strange problem, when I send a message to email address from mail
client like MS Outlook I face immediately Undeliverable message and in the
exim log I found unroutable address this happened just from my mail server
but when I send the message from mail server directly there is no problem
and the message reach the destination email address, so please any idea may
help me I will be very thankful for you
