To state here that I hate spam is a little overkill I think. I don't believe anyone who will ever read this blog will like the offers of MS Office 2003 Pro, viagra, v14gr4, or penis enlargements (well maybe some of this blog's readers would like that ;-).

I do notice that lately spam has been increasing. Either some awful e-mail address CD is out with a lot of my domains on it, or spammers just try to send more in general.

Luckily, my Postfix MTA can scan a message header and body on suspicious text, before accepting it. Especially the body_checks seem to work out rather well for me. I do like to provide the l-user with a message of what went wrong actually (so a human could try again), where possible.

A small list of my mail-header blocking:

/^Subject:.*[Dd]iscount.*$/
   REJECT BLOCKED: too many spam messages with this subject (we do not need 
                   discounts!).Try a different subject.
/^Subject:.*weightloss.*$/                      
   REJECT BLOCKED: How do you know we need to lose weight? Try a different subject.
/^Subject.*[Vv].?[Ii1l|].?[Aa@].?[Gg].?[Rr].?[Aa@].*?/ 
   REJECT BLOCKED: We really do not need help... the natural way works 
                   perfectly! Try a different subject.  
/^Subject:.*Rolex.*$/i                          
   REJECT BLOCKED: We have enough Rolexes by now. Try a different subject.
/^Subject:.* (lotto|lottery) .*$/i              
   REJECT BLOCKED: Never win with the lotto :( Try a different subject!
/^Subject:.*[o0]em soft.*$/i                    
   REJECT BLOCKED: No thanks, Try a different subject! bye.

And a small list of mail-body blocking

/Protected message is attached!/        
   REJECT Thanks, now goodbye!
/MS Office 2003 Pro/                    
   REJECT We think Open Office is better than MS Office 2003 Pro. Goodbye.
/INSTANT DOWNLOAD!/                     
   REJECT The words INSTANT DOWNLOAD detected in mail body. Try an email without these words.
/Stock Alert for/                       
   REJECT Stock Alert? So what? Bye.
/Don't overpay for Bill Gates's crap!/  
   REJECT Thanks, but we don't use Win32 crap to begin with. Bye.
/Pleasure your partner every time/      
   REJECT Partner is very happy, don't need your help. Bye.

Is it just me or has the spam volume increased again?

spam, postfix
