hello,
i need to setup a mail server with postfix + dovecot + webmin + virtualmin + virtual user with linux system user. the virtual user may reach to thousands user from several hundreds virtual domains.
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.
Ben,
the problem is we would use webmin + virtualmin as an interface for costumers to manage their domain (mainly emails) on the server and virtualmin don't use/support mysql + vpopmail yet, at least that what i understand at this moment.
virtualmin choose to use unix system user with postfix, so if i create an email then it create one unix system user too, this is what i'm concern, since i don't have any information about what happen to linux/centos if these unix system user growing bigger and bigger to reach some thousands users for an example.
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.
no particular reason, i just new to postfix, currently i'm qmail + vpopmail admin. i read on postfix and dovecot website about latest stable release and i installed from source :) i know that centos have postfix + dovecot + mysql as a rpm package.
webmin + virtualmin
I've had no experience with either of these as I edit the config files with a text editor.
these webmin + virtualmin mainly for user interface to manage their domain on the server (just like control panel on hosting server)
