Contents

I would like to know exactly where the error is generated 0 Message Author Comment by:Lasareath ID: 379765372012-05-16 SSharma, Well I just tried it right now and it's completely different. Log into Exchange Admin Center.: First we need to log into the Exchange Admin Center. The standard port is 25 for SMTP connections. After the rule is inserted, my problem is resolved and am able to send out mails to external domains. Source

If so, which is the primary (the entry appearing in bold) and is this the smtp domain for the organisation? Home Exchange Server not able to relay to any external domains! Thanks for advance Kams Thursday, January 27, 2011 5:26 AM 0 Sign in to vote
