we have a SBS 2008 with Exchange 2007 - everything i running fine except this Error Message we receive from a single Mail Account we try to send a Mail:
// start of Message we Receive:
Recipient address rejected: Mail appeared to be SPAM or forged. Ask your Mail/DNS-Administrator to correct HELO and DNS MX settings or to get removed from DNSBLs; MTA helo: servername.domain.local, MTA hostname: p578bb76a.dip0.t-ipconnect.de[22.214.171.124] (helo/hostname mismatch) ##
// end of Message
We used to set up a send connector in the Exchange Management Console -> Organisation-Configuration -> Hub Transport -> Send-Connectors
(Sorry for Translation Mistakes - we use a German OS)
There we added the Send conenctos (STMP:*)
This is the Information so far!
Can anyone help me to resolve the Problem?
