Hi. Can somebody help me. The users that I've had moved to the new server are not able to send emails. They stucks in the sending QUEUE with the error that they cannot connect to the SMTP. Is it possible that I can use the old server as a default SMTP? And how to set it?

I'd like to continu testing before moving everybody.
