Has anyone else had problems with sending mail on port 25? It was working fine early last week. I contacted tech support, who said I need to change everything to port 587.
It’s been working fine for literally years, and all of a sudden I have to change ports? Not to mention, I have copiers and other older devices that don’t allow me to change the default SMTP port.
Has anyone else run into this? Was there a service change bulletin I missed?
