Hello,
I updated the firmware on our S2815dn three weeks ago (from 201605200659 to 201610240647) and now I receive error 016-503 "Unable to resolve the e-mail SMTP server hostname". I've tweaked and tweaked the SMTP settings to no avail. I tried restoring to a previous version, and I get a protection error and it cancels the job.
So, how can I resolve the SMTP/DNS errors? We're using Google and here are my settings:
- Outgoing mail server (SMTP): smtp.gmail.com (have also tried smtp-relay.gmail.com )
- Port : 587
- Security type: SSL/TLS
- Email send authentication: SMTP Auth (Auto)
SMTP Server Connection: Unable to connect
Come to think of it, it isn't sending email reports or alerts (duh, of course).
