When testing it here, I got the following:

Source 1 is the lkml source. Source 2 is the kvm-devel source. Some
messages are posted to both mailing lists and end up on both sources.

A message appearing only on kvm-devel is imported normally:

Adding message maildir:/home/ehabkost/mail/kvm-devel-l/#12277020930025949 with state {kvm-devel, unread, inbox}

A message appearing on both sources is imported this way:

Updating message maildir:/home/ehabkost/mail/kvm-devel-l/#12277021040004976, source 1 => 2, offset 12277036400004673 => 12277021040004976, state {lkml, unread, inbox} => {lkml, unread, inbox}

On this case, I would like the kvm-devel label to be applied to the
message, also.

I would even argue that adding the tags configured for both sources
should be the default, but I don't know if there are users relying on
the current behavior, today. What do you think?

Handling the inbox label may be more complicated to implement properly
(especially if some of the sources have the 'archive' flag set and
some don't). But as an user, I expect that a message appearing on both a
non-inbox source and an inbox source would get into the inbox. The problem
would be handling a message appearing on an inbox source after the user
have archived it. On this case, the user may expect the message to not
appear on the inbox again (I am not sure what would be more intuitive).


Additionally, I think it would be nice if sup were aware of when the
message appears multiple times on the sources, instead of rewriting the
source and offset fields. Most times the user doesn't need to be aware
there are multiple versions of a message, but when checking message
headers or other small details of messages coming from different paths,
it would be useful to have both versions available.
