Hi,

/var/log/messages.

You should use the masquerading option in the sendmail.cf:

DMyourdomain.com

The systems thinks you are spamming otherwise.

Here is the messages file, the mail.log will be added later...

The file is cut down a bit, it was to large to upload.

Hope you'll be able to help me!

Regards
Fredrik.

Hello,
From the log file , I can say that you have a DNS trouble...
resolution works for Hotmail and few others, but not for all.
For example I made a test on my side on cactuz.nu, and I had an answer.
In your log file there's no answer.
Can you try on a command line :;
nslookup cactuz.nu.
And send back the answer !!!!
Try also hotmail.com.
..
Hope that help..

hmm... well about this DNS problem.

What can the fault be, is it because the server that runs the DNS is not the same as the one that runs the sendmail???

By the way:
nslookup or dnslookup??

You can use either nslookup or dig -- either should return the address of cactuz.nu . If they don't, then you should look at modifying /etc/resolv.conf to put in a name server that will return an address.

$ dig cactuz.nu
or
$ nslookup -s cactuz.nu (-s tells nslookup not to warn you that the command is depricated)

Happy mailing.
