Hey there dudes

This was the message i have read and my problem is similar!
(http://www.freebsddiary.org/returned-mail.php)

Regarding sendmail error: Data format error (sender domain must exist). I am having the same problem whilst trying to relay mail from an internal networ to an external network (i.e a mail server on the WWW).



This is the error i get

----- The following addresses had permanent fatal errors -----
<user@hotmail.com>

----- Transcript of session follows -----
... while talking to mail.externalisp.com.au.:
>>> MAIL From:<user@internalhost.mydomain.com.au> SIZE=804
<<< 501 5.1.8 Domain of sender address user@internalhost.mydomain.com.au does not exist
501 <user@hotmail.com>... Data format error


I have set up maquerading in the sendmail.cf file but i keep having this error. I need a solution to it! Its driving me insane!

ANyway thanks heaps for all your time and efforts!

Until your box can resolve internalhost.mydomain.com.au to an IP address, you will continue having tht problem. Is that the email address from which you wish to send email? Is that the email address to which you want others to send email?

How can i get it to resolve that name to an IP i have a DNS set up, the hostname and IP are in the dns and its working. I would like to send mail from that address, if it works i will add other users so they can use the internal mail server as well.

Confused...

Please write back.
