Answer 1

Whenever a script tries to login automatically, Gmail generally blocks the script. To enable login through script do this:

1. Go here https://security.google.com/settings/security/activity?hl=en&pli=1
2. In the list of signin, select the one which was blocked and contains the IP of your server.
3. Under Unusual activity click Change and Recognize the activity as yours.

If you do not have the activity in the list goto https://accounts.google.com/b/0/DisplayUnlockCaptcha and then try.

Both Tricks worked for me many times.
