Hi there,

I've glanced through the maildrop filter guides on http://www.flounder.net/~mrsam/maildrop/maildropfilter.html

On the section where it says Predefined variables it shows a var like "FROM" which I could make filter rule base on the sender e-mail addresses. I was wondering why a var like "TO" isn't listed so I could filter base on to whom e-mails are sent? Or even a var like "SUBJECT"?

Right now I'm just making filter rule with regex. Such as

if (/^To: (.*)ro...@xxx.com/) { to "Maildir/.root/" }

So I could filter mails that sent to specifically root to a particular folder. (The mails under Postfix are redirected to an user account, so I need to single-handed out mails that are sent particularly to root.) I was afraid this pattern matching would make filtering much, much slower since it seems to imply sorting through the entire mail, header and body included, to find the string.

Is that the correct way to do it? Any help or pointers to a reference material would be appreciated. Thanks.
