amavis is VERY cpu intensive i run it on many systems. is there a lot of mail going through the system? is there a lot of big attachments? one of my mail servers didnt dip below load of 8 until i upgraded the system's hardware. amavis is great..but if you got a lotta mail you need more horsepower. also if your using something like UW Imap that can be a cause for very high load as well. i suggest switching to something else like CYRUS which reduces load by a factor of 100-200 (it did for me anyways) im sure there are other good IMAP servers like courier(sp?) but i haven't tried them. same goes for POP3. if your using qpopper or ipop3d those can be causes of high load as well(cyrus has a pop3 server as well, does not cause high load) if you have a lot of mail going through i suggest setting up a raid0 array(or raid 10) for /var/spool and have amavis scan mail off that drive. get SCSI if you can for this. sample mail server config: Average KB/hour of mail: 873kB/H Max KB/hour of mail: 9944.7kB/H Average Mail/hour: 71 Max Mail/hour: 1081 Average System Load: 1.02 Max System Load: 4.09 (Statistics gathered from MRTG over the past ~6 weeks or so) System config: Dual P3-800Mhz Dual 15k RPM Ultra160 SCSI drives raid1 /var/spool single 15k RPM Ultra160 drive (no raid) / 256MB ram 256MB swap Uptime: 74 days Time spent idle: 87.0% Linux 2.2.17+many patches (openwall included) Debian GNU/Linux 2.2r3 sendmail 8.9.3 + amavis Cyrus IMAP/POP Apache Apache+ssl Squirrelmail (webmail front end) Mcafee Antivirus 4.0.70 running amavis 0.2.1. hope this gives you an idea of what to expect when using amavis as far as load goes. nate -- ::: ICQ: 75132336 http://www.aphroland.org/ http://www.linuxpowered.net/ [EMAIL PROTECTED]
