I'm using the SMTP plugin on a site hosted by GreenGeeks.
Intermittently, with no reason I can figure, I get this error on saving a page edit, "There was an unexpected problem communicating with SMTP: Could not open SMTP Port."
I don't know the cause of the error, but I know a reliable fix. If I go to Configuration Settings, put in the email account password again, and save that, it starts working again.
It might work more than twenty times. It might work across days. Or it might error out in the middle of a day's edits.
GreenGeeks says that they find nothing unusual in the mail logs. No failures to authenticate, even when I alert them to the exact time and my IP address.
Any thoughts on what could be happening or how to get better help from GreenGeeks in resolving this?
