Jeremy, While you are completely right spamc/spamd are a better combination for performance, there are no debugging abilities in spamc/spamd where as there are many debugging functionalities in the standalone spamassassin script. The purpose of my example was to help troubleshoot a slow spamassassin installation, not to provide a working solution to the problem. I stand by the fact that running spamassassin with the -D comamndline switch is an effective method of testing spamassassin and the various checks that SA performs.

While that is certainly true, telling spamd to run in the foreground (not adding -d), and to turn on debugging -D is an option, and I'm not sure that it differs at all from running spamassassin -D.

RE: [vchkpw] Spamassassin + Clamav Antivirus + vpopmail
If anybody is interested in some of the performance tweaks we have made to SA, please let me know. Due to the response I got from this post... I have created a down and dirty SA config page... Please keep in mind these are only configuration tweaks... Not actually changes to the SA software. As always SA is limited by your CPU first, Memory second, and network connection third. Anyways here are the tweaks web page: http://www.expresshosting.net/howto/sa.html Tom Walsh
[vchkpw] Spamassassin + Clamav Antivirus + vpopmail
Hi people ! I want to install Spamassassin and Clam Antivirus with vpopmail ! Do you suggest any high speed scanning tool ? I know qmail-scanner.pl, but is this a fast method ? Meanwhile.. My Spamassassin needs aproximately 10 seconds for scanning one message. Is this the normal duration ? My homegrown Mailserver uses vpopmail/qmail and has about 200 Mails per day :) Thanks very much, knom.

I use a known spam message as a test bed for tuning performance of our SpamAssassin installation. You can run: cat /path/to/known/spam/message | spamassassin -D Review the output of this command to determine which processes are taking so long. More than likely you are making DNS calls to RBLs that aren't responding in a timely fashion or are using another service (pyzor, which we have had disabled since December) that is slow to return a response. With proper tuning your SpamAssassin can be made to scan messages in under .6 seconds with a full battary of external tests. (This is even on a 1GHz 512MB AMD Athlon machine.)

Re: [vchkpw] Spamassassin + Clamav Antivirus + vpopmail
Hello, qmail-scanner-queue.pl runs spamassassin, razor2, pyzor, clamav, and its own internal scanner, as well as doing rbl lookups, in under 1 second per message, usually about .8 seconds for me. The 10 second delay as someone pointed out is the default timeout for rbl lookups. I had this problem and I recently groomed my rblsmtpd list. I was using servers that were down. The following list may use some services that are a little agressive, though I now have no (known) issues with valid mails being bounced, but in combination with spamassassin, as well as an address known to many spammers (used to get 80+ per day), a few spams make it into my inbox per week. More info about these hosts can be found through their websites. Also, by following /var/log/qmail/smtpd/current, you can follow rblsmtpd's actions, for debugging, etc. FYI: (live, fast responding rbl hosts as of 1/26/03) snip /usr/local/bin/rblsmtpd \ -r sbl-xbl.spamhaus.org \ -r blackholes.mail-abuse.org \ -r list.dsbl.org \ -r bl.spamcop.net \ -r relays.ordb.org \ -r dnsbl.ahbl.org \ /var/qmail/bin/qmail-smtpd \ snip Regards, Alex Martin http://www.rettc.com knom wrote: Hi people !
