Mail is rejected with error message:
CMR-HDR-OE-EOL

Cleanmail no longer accepts messages created by Microsoft Outlook Express. Microsoft ended support in 2009 and has since been replaced by Windows Mail

This software has not received any security updates for more than 9 years, its use is strongly discouraged.

Nowadays Outlook Express, resp. headers which claim creation by Outlook Express, are almost exclusively used by spammers.

I get the error message “Client host rejected: cannot find your reverse hostname” – what does it mean?
