He stated here, and in his numerous posts on the other mailing lists, that he had only a few Mac OS X client machines, so I had assumed he was thinking about some other client. 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. 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.
