 Difficult to say. I also have the same setup and there is definitely some
delay when sending messages, but it's of order of a second, not a minute.
Of course, this is when the IMAP server is on the LAN, it could be worse if
it's further away and the message (which needs to be uploaded to it) is
big. I guess my answer to this problem would be the same as always: try
running it under debugger and break into it when it hangs to see what
exactly is it doing. Maybe do it a couple of times, i.e. continue after the
break, then break again etc. If it really takes a minute, you should have
no trouble debugging it in this way.

 Otherwise there are 2 optimizations you can use for your "Sent" folder:
one is to keep it always open ("keep connection when idle" in the folder
properties dialog) which can help if opening it takes a long time. The
other, and less obvious, one is to clear the "folder tree format" string
for it in "Folder tree" page to prevent M from updating the number of
messages in it after sending the message, as just counting messages can
take quite some time for big folders (but again, by "quite some", I mean
seconds at most, so there is definitely something else going on in your
case, until you run your IMAP server on a toaster or something).

 Good luck,
