Hi !

I really need your help. My employer want to buy Microsoft Exchange, but I need to convince them to use Sendmail (because it's better & free!)

Ok ... now - I have already installed a PC with RedHat 7.2 including Sendmail.

So, how do I make a Sendmail that will be a simple e-mail server for a small LAN of 25 computers ?

All I need is .... a user on a PC to email another user on a PC via Sendmail !

Please! Please ! ... Help :@)

I really suggest uninstall Sendmail and install a different email server called Postfix.

It's a lot easier to install/manage/maintain/configure than sendmail is. It's also a lot more secure. If you read all the security holes found in sendmail over the last years you will be really worried and also makes you doubt whether or not to trust Sendmaill. Postfix is much better.

Other than that, setting it up goes basically like this:

1) Install a pop3 server or imap server on your currently sendmail server.

2) for each user on your LAN, create a useraccount on the sendmail server.

3) done

you can send emails to any of the 25 users on the LAN (assuming that every PC has one person who works on it). They just have to fire up their email client to download the mail from the mailserver. Just like they would do using an ISP.

You could even go as far as installing a webmail package on the server so people can check their email with their webbrowser (and still able to downlaod their mail to their email clients the regular way).

There are some other things you may want to do security wise. Like disallowing those people to login to the mailserver using ssh or some other terminal emulation program (like *shudder* telnet *shudder*)


But that's for another thread.

Big thanks there !

I'll give postfix a spin later in the week :-)
