At this time, when replies are made to a message board thread from the email client, the Subject Prefix is appended to each subsequent reply. It appears that the appending of the Subject Prefix to each reply from the email client IDs the reply so that it is posted to the Message Board. This appending causes the subject of replies to take the following form after some time, thus making the subject unusable:
Re: [Category Name] Re: [Category Name] Re: [Category Name] Re: [Category Name] ThreadName
It would be preferable if additional subject prefixes are not appended to each subsequent reply if one already exists. In other words, the Subject Prefix should be auto-detected so that no other Subject Prefixes are appended with each reply.
