I looked a bit further.
The primary MX for stbartsfw.org is mail.stbartsfw.org. This MX
apparently receives the mail for sbyam at stbartsfw.org and relays it to
220.127.116.11. Exim answers the port 25 connect to 18.104.22.168,
but it returns the "451 Temporary local problem - please try later:"
to any RCPT TO: that I tried. Possibly it returns 451 for any
'invalid' address, but in any case it appears it is not even trying to
deliver mail to sbyam at stbartsfw.org.
