If you are interested in the details of what is happening try running 
alpine with the extra arguments -d verbose=9,imap=4,flush

You can see what IMAP commands happen when you type a '-' or whatever by 
looking in the debug file and searching for "IMAP DEBUG". If you have a 
custom Index Format that can sometimes cause extra traffic, but we aim to 
group IMAP commands when possible. If you see index lines being drawn out 
of order that is because alpine is sending an aggregate request for info 
on all the visible lines and then it is drawing the lines as the info 
arrives. You might like the results better if you turn on the feature 
"Suppress IMAP Envelope Update". Thanks.
