I mean delorie.com.  The retry message is a standard SMTP message, all
valid mailers should handle it correctly.  I can whitelist people who

Greylisting stops a couple thousand spam mails each day.

Yes.  Each combination of from/to/IPaddress is handled separately, but
the content of the mail is ignored.
