Hmmm strange one. The X# Forum mailserver is not in the Spam/Blocked IP addresses of the ISP mail/firewall servers. Also checked no attachments, bad words, NOTHING. We cannot pinpoint why it is rejected...
This email from IP 18.104.22.168 has been rejected.
Strange though, mail messages from Robert/Chris to me does get delivered.
Anyway hopefully we find the magic trick somewhere.
