FYI, this is the most often requested feature for, 
alongside with "give me a mbox.gz with all followups, regardless to 
which list they were sent."

I think several virtual inboxes makes more sense than always one global 
search, as people may want to search something like "all Linux kernel 
discussions" or "all gcc/compiler discussions". There could be different 
frontends to indicate which search is running -- e.g.  
"" vs. "".

As an off-side grumbling, we found out that AWS SES (their email 
processing service) will force-rewrite all message IDs without any 
option to prevent this. So, a single message with multiple recipients 
will arrive with a unique Message-ID to each one of them.

This is so broken, it blows my mind, but AWS doesn't care to fix it.

I hope things improve on the West Coast soon. The imagery alone was 
frightening to watch.
