Things to check;
- is a mail daemon running on the destination machine
- is it set to listen on the correct ip address and correct tcp port
- if necessary restart the mail server on receiving machine - any errors in the log?
Error no only that the mail is in the queue
status=deferred (connect to mail.xx.de[8x.xx.xx.xx]:25: No route to host) - 1 example
- is your networking config good (probably is, as you said you can send email to gmail)
I think it is all right because a mail to gmail is send without problem
it can be the rdns/ptr dns record i think but this one is already set
