Using SBS 2003 and Exchange 2003.
when i try to send a message to this domain only (everything else works) i get the following Error:
Could not deliver the message in the time limit specified. Please retry or contact your administrator.
this happens after 2 days from the time i sent the original email, since retry time is 48 hours. i have receieved email from the other Co. so i know their email is valid, when i track the email in Exchange message tracking center , there is a attempt delivery every 30 min.
10:00 : SMTP: Started outbound transfer of a message
10:01 message transferred to through SMTP
10:16 : SMTP: Started outbound transfer of a message
10:16 message transferred to through SMTP
10:31 : SMTP: Started outbound transfer of a message
10:31 message transferred to through SMTP
and so on....
any idea why i can only get emails from them, but cant send ?
