It looks that your IMAP server doesn't support SORT command,
Indeed:

Go to message list options menu and select "None" in "Sorting column" fieldset.
That *did help a great deal. I adapted the default sorting in the main.conf and things are a lot faster now. Thanks!
Now it's the actual message headers

Each one of those calls takes some time (about 0.07 secs), and for folders with more than 1500 messages in it that's sums up to about 2 minutes. This is were the delay sits. I'm not sure about the implications. Would that mean that the connection to the server is slow?
It looks that your IMAP server doesn't support SORT command, so only solution is to use default sorting. Go to message list options menu and select "None" in "Sorting column" fieldset.
