I have a couple of Xeams servers configured identically. Each server is configured as a Smart Host for our actual e-mail server. As of last night, messages are building up in the queue for each server and when I click on the icon to resend a message, I get the following:
Xeams Admin Console - Version 5.3, build 5858
Error: Unable to connect to remote SMTP server. Unknown SMTP host: ALLDOMAINS
Thanks!
