We have recently upgraded to 5.0.8
I have a mail in database that has a Before Mail Arrives agent that looks at who the email was sent to (multiple addresses goto that db) and issues a forward to the relevant person.
Most documents are now stuck in the MAIL.BOX database with the error "Can't change document's UNID"
I am not trying to change the UNID!! The messages all got through fine before the upgrade.
has anyone come across this or a fix?
