can anyone here help me with the Postfix application and a web form w/ a perl script?

Ummmmm.... no.

I can try. What's the trouble?

have you installed postfix on red hat before? i had trouble w/ sendmail because there were so many goddamn config files to monkey with. maybe i should email you, or you can email me? at the very least i could email you the form and the script and see if what i have should work at least theoretically.
