hi all, i have one question. I am going to start a security companie. I know, every person must choose its own mailserver software. I have tryed out qmail, exim and a little bit postfix. Qmail seams to be very secure and very fast. The configuration i think is to difficult vor every System. Now my choice is exim. Exim works fine and the configuration is simple. Now my question:
why schould i not use exim for my customers? Is it insecure? (i have read the mailinglists and there is nothing i have heard about) das exim not handle a big mail site like 1000 users? thx for your help. thomas On Thu, Jan 17, 2002 at 11:15:49PM +0100, Volker Tanger wrote: > Greetings! > > On Thu, Jan 17, 2002 at 07:06:37AM +0100, eim wrote: > > > > I was thinking about a partition for /, one for boot, one for > > /var/spool/mail and some other important system parts. > > As you want to use exim and mailing list, you will want to have a > partition for /var or /var/spool instead of /var/spool/mail as the > exim outgoing queue is at /var/spool/exim.
