Mail.app definitely spawns large numbers of TCP connections to the
IMAP server (dovecot 1.x) for me. On "Go online" I see one IMAP
connection per folder (*). Longer term Mail.app appears to keep
5-15 IMAP connections open at any one time. My use appears to
generate, from daily stats, on average one connection every 5-10
seconds or so.
Again, not the list...
Speaking purely as someone who has implemented mail clients before, I
can easily see how certain types of object oriented encapsulation of
transport sessions within mailbox sessions as instances rather than
references could result in a mailbox:transport cardinality of 1:1
instead of N:1, as a design simplification of the object model used
within the mail client.
Speaking purely as a former contributor to the Cyrus IMAP server
project and former technical lead on several commercial IMAP server
products, I think you should file a bug.
Can we be done now?
