Hi,
I have recently done a portupgrade after a binary upgrade from FreeBSD-4.8 to
4.9
One of the results was an upgrade from SpamAssassin 2.53 to 2.63 (and also
perl update i think).
I have Spamd running on two mailservers (running freebsd) with user
preferences from SQL. I also use AWL and Bayes Filtering.
AWL and bayes_* is stored in /home/vpopmail/.spamassassin and .spamassassin
directory is a symlink to a directory on NFS.
Before the Upgrade from SA 2.53 to 2.63, I read in the documentation about the
requirement of installing DB_File and doing sa-learn --import afterwards to
get your old bayes db back.
So all that is done, except it slowed down significantly.
I have changed the SA Makefile in ports so that Razor is not installed because
when it is, I cannot seem to get it disabled from
etc/mail/spamassassin/local.cf using a line "use_razor2 0" as documented!
Perhaps a bug?
I also noticed a new DNS check which slowed down the average transaction
significantly (at least 5-10 seconds) despite the fact that I am using two
redundant DNSCache's
So I added "dns_available no" to local.cf and that helped a lot ("yes" didn't
seem to do much better)
I also have the following even from before the upgrade from 2.53:
skip_rbl_checks 1
use_razor2 0
use_dcc 0
use_pyzor 0
The average message (2k size) used to get processed by spamc in 0.1-0.5 secs
Now message can take 1-5 secs to process a 2k size message
Could this be because of the changes in Bayes to use DB_File and a problem
with NFS?
We use a bunch of services like qmail, courierimap, pureftpd, apache, etc.. on
the NFS server and we haven't had any locking/caching problems.
The clients (2 mail servers) are FreeBSD 4.9
I installed the latest DB_File using CPAN shell.
Any comments/suggestions would be greatly appreciated
Respectfully,
Tim Hasson
