Hi,
I would like to know if the Postfix 'wrapper' program will start the spamd or clamd if the daemons when new email arrives, if they do not start on system boot.
No, I've never heard of it being done like that - and FWIW a spamassassin/clamav startup for every incoming mail would bring a machine to it's knees in the event of any appreciable email traffic.
For a large server, that might be true. For a personal machine, or a mail server for a small company, its just not a problem.
The standard suse setup is to launch clamd and amavisd at boot. Amavisd turn loads the spamassassin libraries into memory and waits for incoming messages.
Spamassassin is launched by amavisd once for each email. Amavis does not use spamd/spamc. Amavisd also forces you to use site-wide bayes databases. Its a real mixed blessing. I wish the amavis developers were not so arrogant as to assume they know best.
Postfix passes messages to amavisd after whatever sanity checks are configured. amavisd passes the messages through clamd and spamassassin, and if clean, they are sent back to postfix for delivery to the user.
It's a fairly efficient setup, our amavis servers routinely churn through several hundred messages a minute.
While we are on the subject. Would someone please explain what Kmail does? Seems to be pretty efficient,
Bob: Kmail merely calls spamassassin with each message. Spamassassin simply inserts headers to indicate the spam score, and kmail accepts the revised message. Don't let Kmail do this if you are running spamassassin in the more conventional installation (in conjunction with postfix or sendmail). The kmail method works great with pop accounts. -- ----------JSA--------- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
