smart host not responding
Posted on 2009-04-06
We are in the middle of moving to a new ISP. I tried switching us over to the new connection and had not problem with general connectivity, however our Exchange server could not seem to connect to the new ISPs SMTP to forward outbound mail. Can all SMTP servers act as a smart host for Exchange, or do they have to be specially configured to allow Exchange to connect to forward mail? Our ISP has not stated either way whether they have an Exchange smart host available; they just say they have an SMTP server.
