Forum posts have a message-ID, that does not comply with RFC-2822 and are therefore marked as SPAM messages. The message-Id now looks like this:
18543f025334017e9c1714c1515ece93c1c34efa8633de38535522f916a6eebe
should look like:
18543f025334017e9c1714c1515ece93c1c34efa8633de38535522f916a6eebe@example.com

To reproduce you have to use SpamAssassin 3.2.5

Another thing is, that also the long message ID increases the SPAM-level, but not that much as the invalid messageID
Solution: add @wwwroot (without http) to the message ID, or the SMTP-server address, also possible generate a little shorter message IDs
- is a regression caused by

MDL-30698 Message-ID causes mail problem when sending to more than one person (e.g. forum subscription)
