I'll be honest with you. I can't stand Gmail. I'd never touch it again if I had a choice. The account already in use is only used for sending notifications for the wordpress blogs. I don't think I've sent a message on it for 2 or 3 years. If I knew of some other service not requiring this hoop jumping festival, I'd use it in a second. Personally I don't need the extra secure 2 step verification unless it were required to get this working so I'd rather if possible use the existing account.
Above please see the relevant screens. The password is definitely correct. I might wonder if it were the older version of PHP I have, but as I say, all 3 WordPress blogs on this same server send fine with this exact gmail account..

I apologize for being a pain and reiterate yet again how much I appreciate the help.
