Thanks..

I'll try that.
 

I've configured Mercury32 to block all emails if they have no subject.
This works very well.. The email is block and the users get the normal Outlook error.. Which they never read and then complain that the email wasn't sent..

Is there anyway to create a filter that will email them a new message telling them their email was not sent due to no subject line ??

Thanks


 

Theoretically yes. You could set up a global 'expression' filtering rule like:

---

If not expression headers matches "Subject:*[A-Za-z0-9]*" Goto "NoSubject"

Label "NoSubject"
If header "FRE" contains "@your.domain" SendTemplate "C:\\MERCURY\\NoSubject.mer"

---

and then delete the mail, archive it or whatever. It should let mails pass which have at least one valid char in the subject and only send reply templates to senders within your domain.
