553 errors

[Shannon @ shaw]

I have tried sending from an actual gmail account as well as a domain that uses “Google for Business” but have their own private domain.
So still a wee bit odd.
Anyway, it has to take a back-seat to other, more important things right now.
Thanks for all the suggestions.

>mysql) ? what happens if you create a google account and send an email from there, same symptoms ?

>553 5.3.0 ... Address does not exist 
>553 5.3.0 ... No such user
