If Mail does this then you *definitely* should file a bug. 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. (*) The IMAP server logs are filled with lines like this. I have 335 folders and 335 pairs of lines like this per one "Go online."
