installed qmail- doesn't work -help

[Ben98SentraSE]

Yesterday we got DSL at work with a static IP (YEA!) and it's working great for outgoing internet traffic. Problem is McLeod USA's outgoing mail server doesn't allow email to be relayed that doesn't have an @mcleodusa.net at the end, therefore we cannot send email using our old email addresses. Welp, I have a linux server here with sendmail configured and ready to get our domain's MX record changed to point to it and have email at our domain adminned in house by yours truly. Well I could send via that box, but it wouldn't go anywhere, just into the mail queue and sit. I am a linuxconf sendmail configurer (which is pathetic, I know) and could not figure out how to get to it go out to the net. My friends (who aren't online right now) use qmail and say that it's so much more secure than sendmail and easier to configure too. So I download it, take the time to read all the install docs and do it right. Well I got it up and running, but when you telnet to port 25 it opens the connection and IMMEDIATELY closes it whether you telnet to it locally or remotely. I have NO idea where to go from here. We need to send email! Help!

Ok, I havent gotten the chance to use qmail much (although Im in the middle of the SAMS book on it just more immediate things that I need to do blah) but if you telnet with normal telnet MANY mail servers will disconnect you. Telnet sends each character seperately. You need to only send characters when you press enter. Block mode transfer or something. Check out the man page. Also SAMS publishing has a qmail book. If you are going to be using it I recommend buying the book

Try connecting to it using a mail client (pine, mutt on the local machine should be fine). Let us know what happens.

Outlook Express says that the TCP/IP connection was unexpectedly terminated when trying to send through it. So it's pretty much the same thing as telnetting in. I worked at an ISP for a year and if you couldn't telnet to port 25 on an smtp server and be able to get a response and send commands to it, it was broke. But you may be right

Some smtp servers can accept telnet connections just fine. But as a security feature or something some mail servers will not accept normal telnet connections. I cant remember which servers did this though. I just downloaded qmail and I will get around to configuring it soon. Ill see if I can help you out more then.

Maybe seeing some of the configurations you did would help.

I just followed the INSTALL instructions. Would it help to see certain config files? I don't know which they are so I wouldn't know what to send you. I know linux just enough to be DANGEROUS. I can configure a mail server inside of a network with a port forwarding router with linuxconf but as far as manually editing a sendmail.cf file I am lost. And again I know basically nothing about qmail.

Thanks for your offer to help though.

My qmail buddy is still offline
