I wonder if someone could answer some theoretical speed questions for me. I am using Courier-IMAP to allow users to retrieve mail from my server. So far pretty standard, but the users are all on a high latency, low bandwidth satellite link - 2400 baud, not sure on ping speeds.
At the moment I am getting them to use POP and deleting the messages from the server because there seems to be some overhead in checking that you are only getting new messages, and roundtrip time is a big issue if you are just pulling down 2-10 small messages (along the lines of "Hello Mum", etc) My thought is that perhaps IMAP will offer some benefits here if I can find a client that offers command pipelining. So does anyone know if there are IMAP clients that do pipelining of retrieve commands. Specifically does Outlook Express do this? If so, would anyone like to hazard a guess whether IMAP could reduce the online time for users, lets assume that the average user gets 10 msgs per week and they are all the size of this one or shorter. They can either drag them all down at once with POP, job done, or use IMAP plus pipelining to pull down the messages, but obviously we have to factor in the additional command overhead to check for new messages, etc. Lets assume no attachments for the moment, and that clients want ALL messages, so there are no theoretical gains simply by using IMAP not to download all messages. Is there any way to get Courier IMAP to log it's conversation with the client so that I can see what is going on?
