Which mail server?

Hi,
I am newbe to mail serber. Want to install mail server on my Redhat Linux 9.0 box.

It should give following services.
1) My LAN users are using Win 98, XP with outlook express. They should be able to use outlook express client all facilities to send and receive emails. through mail server. I thought of Exchange server but It will codt me. SO looking for free mail server.
It be possible to use sendmail/qmail server on Linux server and Outlook express on client.

Also advice me which mail server is best suited for this situation.
thansk for support.

Red Hat 9 will have sendmail installed already, But it is hard to configure you could remove it and install postfix for SMTP and install something like Cyrus for imap and pop mail boxes. You could also set up squirrelMail for web access to the imap mail boxes. Do you have a domain name or is it just local mail? you might have some pop mail boxes external of your LAN you could also then configure fetchmail to get these mails hand them to postfix and view all mail with one logon.



"1) My LAN users are using Win 98, XP with outlook express. They should be able to use outlook express client all facilities to send and receive emails.."

The clients can point to either a pop or imap server for mail retrieval and use SMTP for mail delivery. You thought of exchange for mail handling did you want all the bells and whistles. If so you can have these under Linux. It might take a bit more work.

Thanks,
I have installed Redhat 9.0 with sendmal, IMAP and squirrelmail,
I have myown domain and DNS server running on same machine.

After googled I found this howto "http://www.joreybump.com/code/howto/smtpauth.html"

It guides for "STARTTLS and SASL" and SSL certificate.
Let me try it. If it does not work I will come back to you.

Need some more clarification.
If I setup sendmail with SSl certification and encryption. Will allow mail client with SSL as well as normal Login and Password. I mean if mail client does not have SSL facility will he be allowed to access to his mail account on sendmail?

Thanks for support.

I know very little on this but if you set up SSL your clients will have to be SSL enabled. I'm not sure if you can set-up sendmail for both SSL and plain text. I would imagine this would defeat the purpose of setting up SSL. That could be a silly thought.
But let me you ask you this if your clients are internal LAN users why the SSL also if there retrieving mail from external sources using Squirrel Mail make apache SSL instead?

yes,
For internal WINDOWS LAN users using Outlook express SSL is not required. But same users will be accessing outside mails from the server. In this case SSL is not required?
I am not very clear about this. Please guide me.
