You can tune a couple of settings in MailScanner.conf which will help a lot: As each mailscanner process uses about 20Mb of memory you probably want to reduce the number of mailscanner children to 2 or 3. for example: "Max Children = 3" Dont recommend using only one because if that one chokes then the system can stop processing mail altogether. Two or three children decreases that risc. Also if using spamassassin you can set spamassassins timeout high. I have not heard of any drawbacks with this and it saves you lots of worries, and especially so in a system with small resources. for example: "SpamAssassin Timeout = 600" > > See you on the MailScanner users email list (under my work email). also recommended reading: http://wiki.mailscanner.info -- Hilsen from Lars > > -- > Martin > > On 6/1/05, Jean-Paul Natola wrote: >> Hi all, >> >> First OFF NEWBIE here - so please bear with me-- >> >> I have installed FreeBSD 5.4 on a box that I plan to use Mailscanner to >> "filter" the mail prior to hitting my Mail server. >> >> Its on a PII 450 with 256mb ram and a 12 gig drive. >> >> I would like to know >> >> 1) How can I check to make sure the system is running OK ( I'm from the >> windows world) where we have event logs and performance monitor to make >> sure >> the install was done correctly, give you page fault data mem ,cpu usage >> etc... >> >> Any tools or commands in FreeBSD that can give me this type of info? >> >> 2) given the above specs, is that ok to handle mail for roughly 40 >> users? >> >> Thanks in advance >> >> >> >> >> >> Jean-Paul Natola >> Network Administrator >> Information Technology >> Family Care International >> 588 Broadway Suite 503 >> New York, NY 10012 >> Phone:212-941-5300 xt 36 >> Fax: 212-941-5563 >> Mailto: Jnatola@Familycareintl.org >> >> _______________________________________________ >> freebsd-questions@freebsd.org mailing list >> http://lists.freebsd.org/mailman/listinfo/freebsd-questions >> To unsubscribe, send any mail to >> "freebsd-questions-unsubscribe@freebsd.org" >> > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to > "freebsd-questions-unsubscribe@freebsd.org" >
