Re: MF644CDW scan to e-mail issue

If you are using GMAIL:

Username: full gmail address



Port 465 (SSL required)


Port 587 (TLS required)


Ensure you select the correct authentication type depending on the port you use.


For your own knowledge in the future.  Putting a device in the DMZ doesn't help if your ISP is blocking ports.  You can move it back behind your FW once you get mail working.
