Out of curiosity, how many average mail deliveries do you see per hour? And what's the post-processing queue size like?
_____ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Ershad Chowdhury Sent: Wednesday, October 26, 2005 1:08 PM To: [email protected] Subject: Re: [bdlug] Need Information Great answer! I wish I could it sticky it somewhere for reference. My personal favorites are FreeBSD and Debian for servers. I am pretty sure the next release of Ubuntu will also be one of my favorites. No idea about your system loads, but we have pretty high loads and the following steps help: 1. Have more than 1 MX record entry in your DNS and use 2 or more servers 2. partition HDD or use separate HDD (/drool SATA) for mail store, mail queue and virus/spam scanner 3. Lots of RAM Mail server preferences are : exim & postfix. linux bangladesh wrote: >Dear Faysal Abedin > >the answer to your first question is, any distro is as good as you can handle >it.
