SMTP Settings for Sending Through Gmail


New Member
I've tried to follow your directions for setting up for using GMAIL. I don't understand why it's not working. I keep getting an 5.7.8 authentication error while communicating with the server. I feel quite confident that my user name and pass-code is accurate because I successfully login to Gmail everyday. I've tried applying "login" and "plain" under ESMTP authentication. Unsuccessful!

Might "DKIM" have anything to do with it?
What am I missing here?
