Wow, I'd *never* seen that. I don't use local mailboxes much. I guess
you learn something new every day :-)

Not unreasonable. Someone should file an RFE suggesting it. In fact
there are several possible conditions:

* High proportion of messages marked for deletion, for mailboxes with
more than some threshold of total messages (i.e. your test).

* Mailbox is approaching a size limit. For local mboxes, 2.32 apparently
will correct this by using 64-bit indexes. For remote mailboxes, IMAP
servers have a soft/hard quota system but I'm not sure how Evo deals
with it currently. No idea about Exchange, Groupwise etc.

* Running low on space on the filesystem where .evolution lives (for
local mailboxes, whether mbox or maildir).

* Old unexpunged messages (currently you can configure automatic
expunging for these, but some people might prefer to be warned).
