At every CPAN mirror in the world, you'll find a file at authors/01mailrc.txt.gz, with mailing address for everyone who has contributed to the CPAN.

Or even since you mention Text::Template, there's a section at the end of the manpage that says:

  Author

    Mark-Jason Dominus, Plover Systems

    Please send questions and other remarks about this software to
    "mjd-perl-template@pobox.com"
[download]

Or a simple http://www.google.com search for mark-jason dominus turns up a nice bio of him on the first hit, and a link to his homepage on the third hit, with plenty of contact addresses on both.

I'm not sure how you could not know MJD's addresses since it's listed even more places than mine. {grin}

Ahh, rereading, I see you are seeing a temporary nameserver problem with plover. Just retry. At most, that's temporary.
