I'll try to address all of the responses to the best of my ability-
dcass-I'm using MacPerl to edit the script.
Millenium-I'll attach the formmail.pl script in the next post...I looked for a missing/errant semicolon but with my beginner eyes could find nothing. Maybe you'll be able to help.
Chas-It says that version 1.92 was last modified in April of 2002, but I have a strong suspicion that you are right about Matt- I think the last update was done to add the @valid_ENV, by Peter D. Thompson Yezek. I imagine that Matt just stops by the page now and again to make sure it works fine.
Learnhost-I hate to admit it, but "chmod" means little to me. I use the FTP client in Dreamweaver to get to the site, and it's pretty idiot-proof.
