This is not the case; it's not the mail list.  It's the !@#$%
non-RFC-1123-compliant MTA at twics.

What's happening is that TWICS's MTA (sendmail or smail or qmail) is
doing a DNS lookup on the address that your machine gives in the HELO
command of SMTP.  You are required to give a valid hostname according
to RFC 1123, so you're in violation, too.  However, RFC 1123
specifically forbids refusing mail on the basis of the result of a
lookup of that hostname.

Many MTA implementers think this is a stupid restriction, and that
refusing to accept mail from a host with a broken HELO is a smart
anti-spam device.  IMHO they're wrong on both counts, but I don't
implement MTAs....

I still have no idea what you're trying to implement.
