I am monitoring a number of bugs entered into Roundup.

At the moment all the emails I receive are not sorted in 
any way - it's just the order in which they were received.

It would be much nicer if the first email for a new issue 
had a message ID which was stored with the issue. 
Subsequent emails could then have a "In-reply-to" field 
which included that message ID.

Then my email client would thread the messages 
correctly and keep information related to a particular 
issue together.
