Problem with sendmail.
 

Hi!

I have a little problem. I'm trying to get sendmail to send a mail through a smtp-relay.

I have done everything that is explained in this guide: http://cri.ch/linux/docs/sk0009.html

Did a little test to send a mail with echo "Subject: test" | sendmail -v me@domain.com (My own e-mail ofcourse)
Got this back:

WARNING: local host name (burken) is not qualified; see cf/README: WHO AM I?
me@domain.com... Connecting to [127.0.0.1] via relay...
me@domain.com... Deferred: Connection refused by [127.0.0.1]

I seems to me that it's not going through the relay-server at all.
I don't really know what i'm doing..

Hi!
Is your domain name a FQDN ? Is it a dyndns.org domain name ? If it is , did you configure it properly to update your dynamic public ip ? Try to give some more informations !
And also looking at your warning message
Looks like you are sending a mail to internet using only your hostname ...
Bye!

I have dynamic ip so i use dyndns.org. I'm running a program that updates my ip, and that is working like it should.
I'm running Slackware 10.2 with latest sendmail-cf package.

Port 25 is blocked from my internetsupplier so i heard that using their smtp-relay should work.

Actually, i have a homepage where people can comment on pictures, when someone make a comment a message should be sent to my email. And it's that i'm trying to get to work.

I don't understand if you are using your isp as relayhost or dyndns (sorry!) and also what's your MTA ? Anyway why don't you use smtp.gmail.com as relayhost , it works great! If your isp blocks port 25 try using some other port like 465 , 587 , 2525 and make some iptables redirection .
Once again , what's your MTA ? :)

Oh, i'm using my isp as relayhost. Ehm.. isnt sendmail a MTA ? Or am i totally wrong ? I'll try changing relay to smtp.gmail.com. Could also try changing port, but how do i do that ?

I changed the domainname in sendmail.cf and now i get this:

echo "Subject: test" | sendmail -v my@mailadress.com

To me the problem seems to be that the mailadress becomes root@burken. How can i change that to my real adress ?
