GMAIL APP -: Google SMTP Error: 454 4.7.0 Too many

Question

While it was possible to use Gmail/Google Apps as an SMTP server for scripted use or in any other Apps. I started getting error messages:

SMTP Error: 454 4.7.0 Too many login attempts, please try again later.

Sometimes you get, sometimes you don't get such error.

Answer 1

The issue is because of Google Apps Security. You Can't use same E-mail ID with more than 2 Apps. as Gmail needs to sync it, and it is Obvious to receive such error.

Even setting SPF/TXT/DKIM record is not enough for it.

So try to use different E-Mail IDs for Different Apps.
