You're missing the fact that when that server relays the message over to
you, it changes the RCPT TO:.
% swaks -s mail-1.optimalprofit.com -q RCPT -f '<>' -t 'gordonmckee@???'
=== Trying mail-1.optimalprofit.com:25...
=== Connected to mail-1.optimalprofit.com.

You need to make your server accept gordonmckee@???,
or most probably accept helpwhenyouneedit.com as a local domain.
