Sendmail says: .. Domain of sender address [EMAIL PROTECTED] does not exist.
This means sendmail cannot resolve the name. So look at name resolution again. I would suspect the fault there. Note: Sendmail will prefer to use named to resolve names before /etc/hosts. You mentioned internal IP addresses. How do you resolve the name to it?

Folks, when I turn _OFF_ the sendmail feature FEATURE('accept_unresolvable_domains')dnl I start to get the following emails being rejected by my mail hub (I have changed the real domain-name for security reasons - and the IP address is internal only).

Anyone know why it does it and what I can do to fix it ?
