Comment 4 for bug 1034

The issue *I* see with the bugid@.* style email addresses is that it will cause address books to bloat when they are setup to harvest email addresses from incoming messages, which is often the default.

Roundup solves this by having one inbound email address and using the In-Reply-To: header to identify the thread and thus the issue the message was intended for (and Subject: line sniffing as a backup).

We can either solve this the Roundup way or by setting the From: address to something constant, and the Reply-To: address to the bug id.

I don't know if the second solution addresses address book bloat.

The first solution should work, but is complicated by Mark's non-unique message-id fixes he needs to put in to support debbugs syncing. If we ensure that all messages that come from Malone have a unique message-id, then this will not be a problem.

(It does mean that we can't have debugs syncing generate comment emails to bug subscribers though unless we do message-id munging, in which case we can revert to having a UNIQUE message-id).
