Sending email from our server rather than SMTP

[newpersn]

Hi,

 

During our week of crap, we had problem with one user sending out spam emails. Our ISP are not allowing us to be reconnected back to their smtp for outgoing email. (incoming is coming in fine)

 

What is the easiest way of getting our email sent out?

 

(Exchange 2010 running on Server 2008)

Was that user connecting to your internal Exchange box which was then sending it on, or were they connecting directly to the Smart Host? If so, I'm guessing they allowed it to work as an unauthenticated relay and now they won't. You're going to have to use authentication in that case I think. Exchange - Mail Flow - Send Connector - Delivery (this may differ in 2010, that's from my 2013 box). Then sort out the auth settings with your ISP.

dns delivery... it's a radio button on your connector.

Cheers both. Sorted now.
