+When talking to an IMAP server, 
+.I fetchmail
+normally issues an EXPUNGE command after each deletion in order to
+force the deletion to be done immediately.  This is safest when your
+connection to the server is flaky and expensive, as it avoids
+resending duplicate mail after a line hit.  However, on large
+mailboxes the overhead of re-indexing after every message can slam the
+server pretty hard, so if your connection is reliable it is good to do
+expunges less frequently.  If you specify this option to an integer N,
+it tells
+.I fetchmail
+to only issue expunges on every Nth delete.  An argument
+of zero suppresses expunges entirely (so no expunges at all will be
+done until the end of run). 
+This option does not work with ETRN, POP2, or POP3.
