Yea, I saw that thread ...
The Formmail script I downloaded is nasty. I cannot delete one of the folders within it (I'll have to use DOS I reckon) so I don't want it.
It wasn't a foobarred download (I tried twice) and even just deleting individual files within that download took suspiciously long.
I did look at yours Sushubh, but couldn't figure it out :)
I have found a script, and once the sendmail works, it'll do, but given that we have anti-spam measures for comments, and email spam is even more of a problem, I still think it would be a nice bonus to have such a feature in WP.
Putting anything into a Link results in the Link coding being applied, so it's not as straightforward if you want (as I do) a 'contact' link to be similarly styled. Calling a 'formmail.php' can be styled easily, and although there are security risks with having such a script on your site, I'd like to think that given the correct warnings, people would find it useful.
Anyway, I thought I'd add to the WP Wishlist :)
