Optimizing Anti-Spam

[Danita Zanre]

It looks like I can have Mailscanner skip the relay host for the scanning, so maybe I’ll try it.  It would be nice to emulate as closely as possible what the production server will do, but if I have to bypass postscreen/postgrey for now I’ll survive.

Today the spam seems to be better.  I think dcc/pyzor is helping - I’m also not sure that “razor” is doing anything yet.  If I could get MailWatch to work, I’d be almost ready to move a few other subdomains over for heavier testing.

Supposedly postscreen is supposed to be better, although I still use postgrey.  Don't want to use both at the same time, though!

Would you prefer postscreen or postgrey?

Or use postscreen

Also using grey listing will help a lot.  You don't get your mail as "instant" but it really does cut spam down.

Hi dear,

 

I suggest to use razor, pyzor and dcc.

Into a combination of these three, your spam will be counting down immediately! J

I use them on my own system and I’m very happy with it.

 

Kind regards,

 

Miguel

Hi all!  It’s been years since I’ve implemented something like Mailscanner as part of an anti-spam system, but I’ve used various Linux based systems like Maia Mailguard in the distant past.  I've used appliances for quite awhile, but for various reasons have now chosen Mailscanner for the task.  Right now I’m training and tweaking things on a smaller subset domain rather than flipping the switch for my entire system.  I’ve only been running for about 5 days or so.  I’m training the bayes database multiple times a day with both spam and ham, and Spamassassin is now active, but I have a lot of what I consider “obvious” spam leaking through - vulgar words in the subject, sexual content, etc.  While my users will forgive marketing and general “junk”, they will be less forgiving of these things ;-)

 

I’m doing some research on the best settings to optimize.  I used to use things like Razor, DCC, selective greylisting, custom rule sets.  I imagine that these things have changed a lot in the past 10 years.  Can you give me some ideas on some optimizations you use to tighten things up?  

 

Thanks!
