exchange - smtp - relaying
Posted on 2008-10-17
exchange server 2003 (upgraded from 2000) before upgrade this situation was working
Here is situation :
If i use outlook, outlook express, Thunderbird(pop and smtp) to send mail, mail is delivered everywhere so from the point of regular user mail is working.
but if i use telnet exchange.mydomain.local 25, and try to send mail from firstname.lastname@example.org to mail recipient outside company i get NDR.
Your message did not reach some or all of the intended recipients.
The following recipient(s) cannot be reached:
(working mail address from my home) name@homeISP.com on 16.10.2008 16:34
The e-mail address could not be found. Perhaps the recipient moved to a different e-mail organization, or there was a mistake in the address. Check the address and try again.
<.exchange.mydomain.LOCAL #5.1.8 smtp;553 5.1.8 <email@example.com>... Domain of sender address firstname.lastname@example.org does not exist>
If i telnet again and use mail recipient from inside mydomain mail is delivered.
The server(inside LAN) from which i try to send emails is granted to relay (ip address) on properties of smtp protocol .
Any solution ?
