setting up an email server

[bginty4757]

Hey Everyone,

I'm trying to setup an email server (i'm using Redhat 7.3). I've got a domain (www.domainname.com) but i don't have a static IP, i'm using dyndns from dyndns.org. I'm trying to use sendmail, and was wondering if anyone had any links that would walk me through how to configure it? I've heard sendmail is sort of difficult to configure, and I'm just starting to get my feet wet with Linux. Any ideas?

I think that you would need to edit the MX records of your domain to point at your DnynDNS account. You could then install Postfix on your server which is like sendmail, only easier to use.

I may be wrong with the above, but I may be right (i have never done aything like this)

Sendmail on 7.3, if I recall correctly, is distributed already set up. There is no need for any MX records. If the sending station cannot find an MX record, the RFC says it MUST attempt to deliver the mail into port 25 of the domain, exactly what we want. First get the thing working locally. Try this:
echo hello sendmail -v someuser@yourdomain. If you cannot make this work, look in sendmails logs, /var/log/maillog and see what went wrong. If it does, try telnetting into sendmail from outside your domain, this also must work. If that's ok, you should be good to go.
WARNING! I also seem to recall there was some security issue with that version of se\ndmail, or maybe it was sendmail plus that kernel, or something. Look into that, too.

thanks for the posts guys

i have been messing with sendmail for a while now. i think i am going to try postfix - i keep reading that it is easy and i suppose that is what i need. i might stop back here and reread those links again if i find it isn't all that. thanks again

I use qmail and it works like a charm and is fast as hell too.
