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 firstname.lastname@example.org
. 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.
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.
