# 2: mail is still unusable when used by MS Internet Explorer 5 and
# Netscape Communicator 4.61. In IE 5.0 it still produces the same rubbish
# characters in the text and with Communicator it will not even send text.
I did find a minor error and I have baselined a correction that might
have corrupted the output. It didn't here though. A copy is included
below.
Build this, put in your cgi-bin directory and then access it as
http://yoursite.domain/cgi-bin/mail
In answering the other part to your question...
I use
hm_mailcommand = mailto:$TO?subject=$SUBJECT
in my .hmrc files to send the proper information to the mailer.
Works nicely. Or are you looking to use the mail for some other
purpose ?
