Just a wild guess but....trailing spaces

by robo_dev In reply to Relay access denied

oftentimes an extra trailing space gets into a users email address book entry. The result is relay or receipt errors for one recipient only.

This can lead to all kinds of delivery failures because 'space' is a character too. Look REAL close at the logs for spaces after the domain name.
