Hello all, I am looking at building my first Linux email system. I very much would like to use Linux over windows/exchange for all the obvious reasons. The Servers need to host @1400 pop3 accounts. I was wondering if any of you could tell me if it is possible to cluster multiple mail servers for redundancy/performance. What distro / mail server software do you all recommend? Ron I switched to sendmail four years ago and never regretted my decision to do so. Admitedly there have been a couple of security issues in that time but doing the patches saves the heartache. I have looked at failover solutions but can't really comment on clustering because I've never done it up to now. Sendmail hasn't skipped a beat in that time so I never persued it any further. The previous windows solution needed a poke every week to keep it running and I must have saved hours of the 'is the email server running?' questions to more than make up for doing the switch. Have fun which ever solution you pick but I can recommend Sendmail no worries. Bry
