	Hi,
Evolution (libcamel from the evolution-data-server) does not ask, it
lefts the user to decide, using some default (which works for many/most
servers). I do not think IMAP4 has any such command, but I did not try
to search for it.

Evolution does not open all those connections at once, it opens them on
demand, only when needed. You can have set 10 connections to be used
and after hours you'll have only two opened in reality. It depends how
the commands/operations in the account come. Some of them can run in
parallel with others, some cannot. For example downloading messages in
two different folders can run independently, then when there is no free
connection and there can be opened a new one, the new one is opened and
used for the second folder message download.

	Bye,
	Milan
