Since years and years, I use posting by email to transfer newsletters (html messages) to some forums/folders.

Now when I do that, I find the following message in Catalina.out :

ERROR [org.subethamail.smtp.server.Session-/ipaddress:42497] [org.kablink.teaming.module.mail.impl.DefaultEmailP oster] - Error posting the message from: myemailaddress Error: Illegal group reference

If I create a new message with only some text in it, it's working.

Thank you for your help.
