Re: Mailscanner PC requirements
Hi might need more RAM, esp is you plan to use Spamassassin with the MS setup. My old system (cel 500 512MB RAM) would top out around 14,000 messages per day of around 25kb average size. But I was also running MailWatch and the associaed mysql DB on the box as well and lots of extra SA rules.. As for performance related stuff vmstat/iostat/sar are good places to start. Also you don't mention the MTA to be used. This can make a huge difference. Sendmail and Postfix tend to slower with exim and qmail faster in that order. You'll get extra performance by turning on softupdates on the spool directory filesystems too. 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 [EMAIL PROTECTED] 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.

RE: Mailscanner PC requirements
Well our mail store ( is at about 8 gigs) it should never go higher than than that. Should I try to get a # of messages per day tally , would that help? -Original Message- From: Bill Moran [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 01, 2005 12:53 PM To: Jean-Paul Natola Cc: freebsd-questions@freebsd.org Subject: Re: Mailscanner PC requirements Jean-Paul Natola [EMAIL PROTECTED] 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.

Should I go ahead and reinstall it? Installing X on a server is overkill, unless you plan on staring at the monitor all day. OTOH, FreeBSD also makes for a nice desktop system. Better activate sshd (Secure Shell daemon) and log into the machine from your desktop, e.g. with 'putty'. That way you can run commands like 'systat -vmstat' remotely. You can also view the logfiles by logging in remotely. If you are logged in you can also modify syslog.conf to have the system write you a message whenever certain types of error occur. You could even have the system e-mail you the error messages (unless the e-mail isn't working :-) Roland -- R.F.Smith (http://www.xs4all.nl/~rsmith/) Please send e-mail as plain text. public key: http://www.xs4all.nl/~rsmith/pubkey.txt pgpA7NneNo2y2.pgp Description: PGP signature
