I have received so much great help from this forum that I'm going to go for it again!
When we first installed EPDM, the SMTP notification system worked great. Then, our fine IT folks in another state (where the EPDM server exists, sadly) changed the e-mail server. Since then, we cannot use SMTP notifications.
Our IT gurus (who were willing to help) have tried all the fixes that have been suggested in this forum, to no avail.
The "Test Settings" function returns an error that says "Send mail failed Error: 530 5.7.1, Client was not authenticated. Could not send test message." (Image attached)
I can ping the e-mail server IP address, and I have confirmed we are using the correct port, but that exhausts my meager knowledge of troubleshooting.
I will forward any suggestions to the network folks. Thanks in advance!
