One item I would like to see a comment on is how well the mail clients deal with large mailboxes. and large numbers of new messages. as an example of one of the worst clients I've seen for this it can take Outlook hours to find new messages if you have been on vacation and have a few thousand new messages waiting when it starts up (and you don't want to think of what it takes when you point it at a IMAP mailbox with a few tens of thousands of messages sitting in it)
the quality of IMAP support is almost worth an article in itself, a mail client with poor IMAP support treats IMAP as just a means to download messages (a direct replacement for POP), but a client that really uses IMAP can potentially be FAR more responsive.
for example an IMAP client can download just the header info for the first screen worth of mail and then download the rest later (while the user is doing useful work instead of waiting for the client to find the messages).
Also since the IMAP server understands MIME the client can delay downloading attachments until the user indicates that they are interested in doing so.
there's quite a bit more that's possible, but I don't want to make this post TOO big
