Email Server

By lhatcher ·
I am looking at setting up an in house email server. It would need to use imap an pop. There will be around 75-100 users. It will run on Red Hat Linux. Free would be great, but we are willing to pay also. Anyone have any suggestions as to what email server to use?

A number of my installations use Red Hat 9 and Fedora Core 4 with Sendmail, supporting IMAP and POP. You can also run Fetchmail which collects mail from external mailboxes. Procmail allows you to filter messages before delivery or redirection. You can also run Spamassassin and ClamAV antivirus with Sendmail.

If the company uses Outlook as their email client, have a look at Open-Xchange 5 at It has both a commercial and Open Source versions, and its Outlook Oxtender supports calendars, tasks and shared folders. The product supports Palm, too.

From you can download a complete server which runs from Linux Live CD.

A server should be a secure one:


to name a few. All can be configured using
maildirs. (qmail can only do maildirs)
Maildirs are preferred above mailfiles because
there is no need for locking. They can also be
used with networked devices (nfs, cifs/smb).

Imap server:

courier-imap knows about maildirs.

Then there is the question do you need to
integrate spam/.virus checking?

In that case postfix/exim can handle the
connection with f.e. amavisd-new more elegant
than the other two. (you will also need clam-av
(or other virus checkers) and spamassassin
besides amavisd-new to handle mail checking.

squirrellmail can be used as webmail frontend,
and all imap/pop clients can be used with this

you can build an environment that is completely
configured through a webinterface:

The system describes the procedure for gentoo,
there emerge is like rpm on fedora (only it
builds from sources).

Kind regards,
