greetings,
yes, Mr. Richey it was funny what everyone posted... we all need that from time to time eh?
ummm on the work side... i have been trying to search on how to block alternative language spam (spanish or otherwise) and am coming up fairly blank except for Bayesian filtering...
i will probably be using the www.qmailrocks.org system again yet i am interested in what others have done and are doing please...
i used sendmail for years so any hints from that side would be appreciate too please?
plus if someone tell me what i should be putting in my google search for trying to find alternative ways to filter spanish or other language spam please? i am almost drawing a blank!
thanks in advance

Ugh.. qmail. I'll refrain from spitting up too much hate about the DJB way of doing things here and just say "it's a functional product, but his way is not the right way"

There are some excellent mail setup guides located at http://www.hughesjr.com/content/category/1/14/30/Guides
They're quite good, and cover everything from intial setup to webmail to filtering. Well worth the read.

thanks for input!!!
having built many mailservers i will be ok in general yet what i am really looking for now is how is everyone here filtering "spam in languages other than English"... most of the spam i get is in Spanish.
i am having a hard time finding it googling (other than Bayesian filters) and i just need some searching help or direction to find so i can study up please?
and thing is, ummmm im willing to use sendmail yet i want my customers to be able to admin their own virtual mailservers with a web interface... what is everyone using there??? sendmail and ??? or qmail and ???
that is why i choose the www.qmailrocks.org system... i almost always use a command line interface yet i wont do that for clients less they get their own box rented or otherwise.
i do appreciate the pointers Jim as i am not fully up to speed on a few of the newer sendmail etc configs and stuff... thanks again!
thanks!

I find postfix to be quite sexy, but I don't do much in the way of virtual hosting. Postfix in the centosplus repository has support for mysql, and should be what you're looking for but I don't have much detail for you. Postfix is easier to set up than sendmail, and requires less upkeep than qmail (no building it, no patching it, no wondering where the hell djb thinks mail files should go since he's too good for standard locations), not to mention that postfix is provided with the distro, so you'll get updates when they happen, not when you notice them and rebuild.
Just my $0.02

---- - Google offers to translate pages with a sublink on all found items that aren't your primary languages...at least it does for me.
- spam is spam and is not about language. If you want more aggressive spam filtering, perhaps you should investigate a better wrapper (I use MailScanner but my guess is that mime-defang and amvaisd-new are quite capable), implementing more spam features (DCC, pyzor, DNSBL, etc.)
- greylisting (http://www.greylisting.org)
I use postfix, greylisting, MailScanner with spamassassin & clamav, and sieve filters (cyrus-imapd) and get pretty good control. Probably the most significant things I do is to have a fairly comprehensive smtp_helo/smtp_sender checks in postfix and greylisting which gets all the low hanging fruit so I am not sucking massive cpu power on the rest of the checks mandated by MailScanner ----

---- on servers that provide smtp for domains...probably 60% sendmail, 35% postfix, 5% other - just a wild guess - no empirical data whatsoever.

If you are absolutely sold on qmail ... you might try

One option that will eliminate 95%+ spam that is available for most MTAs is greylisting. The combination of greylisting and spamassassin blocks nearly 100% of spam. The added benefit of greylisting is that your system's load won't be pushed due to overhead of running spamassassin on the vast majority of messages.
I implemented milter-greylist/sendmail/procmail on a system for a small company and reduced the number of spam messages from around 8000 a day to about 10 or 15 a day, and those were caught by spamassassin.
You might want to check out http://www.rulesemporium.com/ they have a number of very good rules sets and possibly some examples that may help you write specific rules for the spam you are receiving.

Yes, it is so far wrong and has licensing that prevents others from fixing it that there is a project to completely replace the front end component: http://smtpd.develooper.com/.
I'm not sure why anyone would replace the perfectly functional sendmail/postfix components of Centos with qmail, but if they did it would be a good idea to check out qpsmptpd. It can also be used as a front-end to postfix to give some of the functionality that you get with sendmail milters like MimeDefang.

Hmmm, that's not quite how it happened. qpsmtpd was written by people who _like_ qmail but wanted to be able to do some funky things at smtp time that were never going to work shoehorned into qmail-smtpd. But I second the recommendation.

qpsmtpd also has a vanilla smtp-forward mode so you use it in front of any standard mta. The nice thing qpsmtpd brings to the table (as opposed to things like amavisd, MailScanner, etc.) is the ability to identify and refuse spam at smtp time, often even before the mail data itself has been received, which translates to much lower load. Why accept spam at all to just bounce later?

In code with more reasonable licensing, they could have reused the existing code, adding what they wanted and fixing the broken parts. Since it's qmail, they had to replace an entire component.

Sendmail has that ability when you add suitable processing through the milter interface. The milter(s) run concurrently and can respond at each phase of the smtp conversation so you can reject based on content. MimeDefang is a particularly handy milter because it lets you control all of the things you might want to do (spamassassin, virus scan, network checks, etc.) in one place with a small snippet of perl, and it doesn't affect anything sendmail already handles. For example, why waste the CPU on the spamassassin scan if your access rules already block the sender?
And if the original poster is still reading, there are commercial versions (Canit and Canit Pro) that have additional features like a web interface for individual users to control their spam handling. http://www.mimedefang.org http://www.roaringpenguin.com/

A mix of Sendmail w/ greet pause, throttling, milter-ahead(or sender) milter-greylist, MailScanner with SpamAssassin + DCC + Pyzor + Razor + Rules du jour is what I use and I'm very satisfied with it.
