On 6.4.1 (yes, we should upgrade). Looking for assistance on how to correct RFC 2822 registration and forgotten password email error. The problem appears to be duplicate from email addresses. Should be a pretty easy fix and am willing to pay. Thanks in advance for assistance.

SMTP error from remote mail server after end of data:
