So this is a very odd problem, but I hope someone can help me out.
We have two email address serviced by Google Apps for Dreamhost.
“EMAIL1” can sent and receive emails with no problem, However 'EMAIL2" CANNOT send anything to “EMAIL1”… we get an error.
Interestingly enough, when “EMAIL1” sends an email to “EMAIL2” and “EMAIL2” replies… it goes through.
Both accounts are set as administrators and NOTHING is different from their setting. Please advise!
