wrong mail domainname in maillog?

Hellow focks,

im getting a strange server in my maillog, were does this come from and how to change it to my own server?

Maillog entries:

Jul 15 23:59:33 213-132-175-221-hosted-by postfix/qmgr[28669]: 18D6D2800A8: to=<[email protected]>, orig_to=<[email protected]>, relay=none, delay=341383, status=deferred (delivery temporarily suspended: connect to web8.clusternet.nl[213.247.61.175]: Connection timed out)

WTF is web8.clusternet.nl ?? i didn't put that in any config file....
Someone has a solution?

Really Thanks,

Marvin

 

What's the output of

Code:

hostname -f

? What's in /etc/hosts?

 

[root@213-132-175-221-hosted-by ~]# hostname -f
213-132-175-221-hosted-by.dataregiocentre.com
[root@213-132-175-221-hosted-by ~]#

and in /etc/hosts:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost

 

And what's in /etc/postfix/main.cf?
What's the output of

Code:

ifconfig

?
