Knowledge is power, and you're usually better off knowing than not knowing (what you don't know can hurt you). You're also assuming that most people are clueless, or can't be bothered to defend themselves. What if someone really doesn't like having someone else impersonate him, and decides to go after such parties with a vengeance? They need all the data they can get to present in court. If the person, on the other hand, really doesn't want to know or doesn't care, then let him make the extra effort to filter the bouncers (at his peril). -Philip

RE: Perl Modules?
I have the CentOS 3.2 system going and noticed something when doing research on the perl modules that SA uses. Currently I have Digest-SHA1 installed that came with CentOS and it's version 2.01-15.1. However when checking my control panel software (www.directadmin.com) I saw that when running the script file to update SpamAssassin to 3.1.1, they had downloaded and appearantly installed Digest-SHA1 version 2.10. Likewise I was unable to figure out what version of libhtml-parser-perl I have installed. Anyway, would any of this be leading to problems of STILL getting the 421 BSMTP timeout errors with Exim/SpamAssassin? These problems appear as soon as I start SpamAssassin with messages becoming frozen containing: The following text was generated during the delivery attempt: * -- @teazles.com -- An error was detected while processing a file of BSMTP input. The error message was: 421 Lost incoming connection The SMTP transaction started in line 0. The error was detected in line 3. 0 previous messages were successfully processed. The rest of the batch was abandoned. 421 Lost incoming connection Transaction started in line 0 Error detected in line 3 * Within 5-10 minutes after starting SpamAssassin I had 8 frozen messages and they continued to add up the longer I let SA run. I had to kill the process and comment the SA parts in the exim.conf file to at least allow email to get through to my clients. This has me baffled, and quite honestly frustrated to no end as to why it's refusing to work correctly when it has in the past.

Even with the best settings SQL is slower than even DBM in phase 1, which is all learning. I'm a little surprised at your result however.. Such a huge difference implies that SQLite isn't doing nearly as well as Mysql/pgsql. The worst-case phase 1 difference was 436% slower for SQL than SDBM, but your results are on the order of 18000% slower.. Where SQL seems to shine is in force-expire (phase 3), and it does well in scan (phase 2 and 5). It also seems to do poorly in the forget (phase 4). At first you might think force expire and forget should be delete based, and thus similar, but in reality force-expire is read/delete intensive, but forget is update intensive, with few records deleted. Based on that it appears: SQL does better than DBM at reading SA bayes records SQL does better than DBM at deleting SA bayes records SQL does worse than DBM at inserts. SQL does worse than DBM at updates. Whereas SDBM does better than DBM in all tests.

So I backuped my bayes db (around 10mib) and restored it with the sqlite module, which took several hours. Using SDBM it was a matter of 20 seconds (so I can confirm what Michael wrote). I don't think SQLite itself is _that_ slow (in fact, I don't think it's slow at all), it's most probably a matter of optimization, but the additional SQL layer will surely not speed up things and SDBM seems to be quite fast. If time permits, I'll do a benchmark run, anyway, and post it here. Regards, Jakob

You're welcome to try SQLite, but all testing I did was too slow to even wait for results (multi-day runs vs multi-hour for other slow systems). The bayes storage module is such that you can modify the various queries to work better with whatever engine you would like (see Pg modifications). If a SQLite expert wants to take up the challenge and provide patches I'll happily review them for inclusion in the code. Michael

I chose it for better speed than dbm, without the extra ram overhead of mysql. I posted some questions about this in December, with no real response: http://mail-archives.apache.org/mod_mbox/spamassassin-users/200512.mbox/[EMAIL PROTECTED] I'd be interested in hearing any results you get from using sqlite... As for SDBM, I'll warn you that if you're not using SA 3.1.1, there's a bug in sa-learn --restore that affects sdbm. http://issues.apache.org/SpamAssassin/show_bug.cgi?id=4670 That said, I've been running bayes with SDBM in production since December, using SA 3.1.0, and am fairly happy with it.

What Perl modules does SA require? I'm looking into this as being a possible cause of my 421 SMTP timeout errors.
Bayes store recommendation
Hi everyone, I've searched a little through the archive but found not much about that. Right now I'm using DBM for bayes. I know the officially recommended storage is a SQL DB (though I don't know why). I have a mysql server running on my mail system and tried using it for bayes a while ago (with SA 3.1.0) but didn't see lower scan times. For a local RDBMS I think SQLite is a very good thing, but there was a list post where somebody said ist not suitable for SA (though README.bayes mentions it). According to the bayes benchmark in the wiki (http://wiki.apache.org/spamassassin/BayesBenchmarkResults), SDBM is the fastest store (though there are no sqlite numbers), but I wonder why it's not mentioned much. I'll probably run the bayes benchmark myself (with sqlite, sdbm and dbm), but somebody has probably some experience to share. Regards, Jakob
