Still happening. But when you read the error message that's not
surprising, because it seems to be an SMTP server setup issue.
pythoncraft.com's SMTP server's Postscript doesn't know who "aahz" is.

Yes, but the MX setup for holdenweb.com is also broken:

Host/Domain: holdenweb.com
MX: aspmx.l.google.com(10)
MX: alt2.aspmx.l.google.com(20)
MX: alt1.aspmx.l.google.com(20)
MX: asmpx3.googlemail.com(50)
asmpx3.googlemail.com NXDOMAIN
MX: asmpx5.googlemail.com(50)
asmpx5.googlemail.com NXDOMAIN

Remove the two non existing MX records (NXDOMAIN)

aahz@pythoncraft.com

That one seems to work again.
