Update...I configured a Savin 917 in one of the locations and it works fine also. Had another customer call with Savin C9120 with same problem. Put the settings in a C9120 here and it worked fine.
We have a Comcast business account and use that mail server for all of our MFPs. Never had a problem with it until around August 29th. Been using this for 5+ years.
Does anyone know how to configure the SMTP server settings for Gmail? I used my login information, port 465 but didn't see if/where SSL needs to be turned on. Is it a given that 465 is SSL?
