Hi everyone. It's my first time to post a thread on this website. Ok.
I'm the IT manager for a small entreprise. I try since 2 months to setup a samba server, a DNS server, a http server and a stmp server. all others servers are ok except the smtp server. I choose sendmail as MTA but really it's to difficult very to setup with it. this is the reason why i post this thread.
let's me explain the situation. all of employees have an email account provided by an ISP and it looks like xxx@ISP.tld. what we want is to setup a our own smtp server with emails like xxxx@ourdomainname.tld. for that we got an official domain name from the ISP. I think i explained the situation so i'm waiting forward yours helps. Thanks.

YOu have not stated what exactly your problem is. You have merely told us that you have an idea of what you want but this does not relate in anyway to the problem you have....which as you can see you have note elaborated..

Do you want details of how to set up a mail server using sendmail? If so what distro dyou want to use? Number of users......


Get my drift?

excuse me i left the forum. As you said yes i want details of how to set up a mail server with sendmail with information i said. I'm using Redhat as distro and the number of users is about 40 in the entreprise. i apologize again for my delaying. thanks.

Ok so you want to install a mail server. You have to ask yourself a few questions before going through with it:

1- Is sendmail the answer to a small mail server ?

I'd quickly say no. Most admins nowadays use easier (I might get bashed for this) MTA's as sendmail is huge, old and clunky. I'd suggest postfix or exim. Very easy to configure and tons of documentation.

2- Do you have local users or do you need a database ?

Do you have Active Directory in your small enterprise ? LDAP ? If so, integration from postfix to AD can be tedious. LDAP is easy. If not, move on to next question.

3- Does your ISP let port 25 outgoing ?

Probabilities are that yes they do seeing as you must have a commercial internet connection. I'd test from my server to make sure, something like: telnet <isp mail server> 25.

There you have my 2 cents.

Cheers,

ok. sendmail is the most difficult MTA. I thought for leaving Sendmail to another MTA. i'm feed up about it. Postfix is more secure than sendmail?.
supposing I took Postfix, how can i setup Postfix in my situation. thanks

Hi there,

Here is a quick and simple howto. Install the postfix package and then give this a shot.

ok thanks mtimbro. I'll keep you in touch about the situation. again thanks.
