I'm looking for a Perl developer with MIMEDefang experience for

I'm interested.
I've been using Perl for approaching 20 years. I can't now remember
when I started using it, but I was writing mod_perl scripts for Apache
Webservers around the turn of the century for a legal training firm in
Los Angeles which had in excess of four million users (unfortunately I
can't identify the firm, which is still in business and my contract
still binds me to confidentiality). Before that I coded some of the
early sites for an online holiday site which was then owned by EMAP
Publications in the UK - I think that was my first Perl contract.
Also at about that time, together with Stas Bekman I re-wrote and
greatly extended the 'Mod_perl Guide'.
I've been using MIMEDefang for over nine years in both my own and
client mail servers. I try to minimize the number of messages which
are scanned by heavyweight Perl scripts, and MIMEDefang is generally
the last in a string of about seven Sendmail milters.
I wouldn't describe myself as primarily a Perl developer. I have a
very wide range of experience with GNU/Linux systems, mostly based on
Debian, Red Hat and Slackware distributions. The attached list is to
be the basis of a training course which I'm planning for a client, I've
quickly hacked it to avoid identifying the client and to remove some of
the less interesting items.
I'm based in the UK and France. I have business interests in the UK,
and a home in the French Pyrenees.
Where are you based?
Kind regards,
