That shouldn't be a problem. Postfix has had support for this for well over a decade. > what i concern is large numbers of linux system user which used in > these setup, is it good or bad? Virtual users with a Postfix/Dovecot installation does not equate to real Linux/shell accounts. If the only service being provided is mail, then there's no reason to create real accounts. > maybe somebody would share their experience about this setup ? > > any links would be good. > > postfix 2.6.7 > dovecot 2.0.6 > centos 5.x Is there any particular reason you've chosen these versions? That is, are there specific functions which these versions provide that are not in prior versions? I ask because I'm running these versions in CentOS 5.x: postfix-2.3.3-2.1.el5_2.i386 dovecot-1.0.7-7.el5.i386 If the only concern is security updates, these are backported to the current versions in CentOS. > webmin + virtualmin I've had no experience with either of these as I edit the config files with a text editor.
