In future, it might be more effective to send directly to the postmasters
at the hosts in such a message (and also more secure since you're not
revealing the list to anyone else).

A grep type replace of the characters before the @ symbol with "postmaster"
would produce the necessary To: field contents.

E.g., replace [^\ \,\r\n\t]+@([^\ \,\r\n\t]+) with postmaster@\1

There's probably a cleaner way to write that, but I tried it on the To:
field in the message from your web site, and it did the job. (I didn't send
the message, only tried the grep pattern)
