I've been following this Google Apps support page to be able to set up scan-to-email using the Gmail SMTP server. The printer is a Samsung CLX-6260 FW.
I've configured it with the following information:
SMTP Server:
smtp.gmail.com
Port Number:465
SMTP Requires Authentication:Yes
- Login ID:<my Google Apps email>
- Password:<my Google Apps email password>
Secure E-Mail Connection with SSL/TLS:Enabled
SMTP Server Connection Timeout:30
But whenever I test the connection, it fails with a server timeout. I've tried increasing the connection timeout limit, but that doesn't seem to work. Has anyone managed to set this up successfully? How did you do it?
UPDATE: I tried out port 587 and that started working. Haven't gotten around to testing with a VPS, but the output of openssl s_client -connect smtp.gmail.com:465 shows that the connection does work from our network, so if anyone out there knows what the answer might be, I'd love to hear it!

You may want to check if your ISP is blocking port 25. – Tanner Faulkner – 2014-07-17T15:14:12.110
Do you have a linux VPS you can use for testing? I'd try listening with netcat, something like
nc -vv -l 465, then configure the printer to connect to your VPS instead of Google's mail server. This could help to confirm if there's a routing problem. – jon – 2014-07-17T16:25:28.783I had a similar question. It seems that Gmail only allows OAuth 2.0 authentication, but you can enable other methods in account settings. http://superuser.com/questions/987842/why-can-i-authenticate-to-my-gmail-account-neither-from-my-printer-nor-from-my
