Yes - you can use multiple SA servers talking to a common MySQL
database. I'm doing it with about 5 servers and it works. The answer to
question 2 is - YES.
I'm using Exim for an MTA and I use white lists and black lists to
prefilter spam. That greatly reduces the SA load.

Hello guys,
I'm running a small-sized hosting provider and currently our setup is
following:
1 mailbox server running exim (only local delivery)
1 antispam server running exim + mailscanner + spamassassin +
mailwatch -> sends all approved mail to mailbox server
2 mysql servers (master-slave) running databases for mailwatch +
spamassassin (bayes)
I have two questions about this, hope someone can help me.
1. Because all the load goes to the smtp server now and to add some
redundancy to our setup, we would like to add another antispam server,
with the same setup (which is working fine). Will this be possible
(concerning spamassassin), with two nodes sharing the same bayes
database on the mysql servers? Is it possible to have two nodes
feeding the same bayes database?
2. On my mailbox server I'd like to have a script which goes into the
mailfolders, searches for a folder with the name 'Spam', feeds the
message to sa-learn (which should be feeding it to the same bayes
database of course), and then delete the message. Do you think this is
a well-thought approach of having my users train the spam filters this
way? Maybe there are already such scripts available?
Thanks in advance,
Peter
