Like (I guess) many people round here I'm getting Too Much Email that I don't want to read. So I'm doing something about it. Using Perl. And no, of course, no-one elses solution will work just how I want it to work so I'm in full wheel-reinvention mode.
The biggest problem I'm currently having is bounces from spam that has fake addresses in my domains as the 'From:' header, so that's the problem I'm addressing first. I have a finite number of email addresses that I want to read email for and any email addressed to a different address will be filtered off to a different folder for later investigation. I hacked up something that identified the emails I want to filter using Email::Simple, but I'd appreciate some input on what I've done. There are three areas I need help on. Problem the first. The first problem is identifying why the email ended up in my inbox. I need to work out which of the many email addresses in the many headers is aimed at me. Here's the algorithm I'm using. 1/ If there's an 'Envelope-to' header then use that and stop looking. 2/ Otherwise look for email in 'To' and 'Cc'. If something likely is fond then stop looking. 3/ Otherwise start poking around in the 'Received' headers. Can anyone see a problem with that? Problem the second. I'm using the Email::* modules but there doesn't seem to be a way to extract the actual deliverable email address from the headers. For example, from "Dave Cross" <[EMAIL PROTECTED]> I need [EMAIL PROTECTED] Currently I'm using a nasty regex hack. Bear in mind tha some nasty email clients do stupid things like "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> or even "'[EMAIL PROTECTED]'" <[EMAIL PROTECTED]> Email parsing is listed as "for a future release" in Regexp::Common. I could use Mail::Address, but I don't really want to install Mail-Tools given that Email::* replaces most of it. Any other suggestions? Should I just write Email::Address and submit it to the Email::* project? Problem the third. I use procmail for my mail filtering, so I need to plug this new filter in with that. The processing I need is: if email is to a dodgy address then save it in 'notme' mailbox else continue with normal procmail processing end But my procmail powers are weak and I can't work out how to do it. I see that spamassassin adds a new header to the email and my next procmail rules does the filtering. That would be an acceptable solution if I can't do it all in one rule. Any help and advice on all of these issues much appreciated. Dave... -- <http://www.dave.org.uk> "Let me see you make decisions, without your television" - Depeche Mode (Stripped)
