+@cindex IMAP debugging
+@cindex protocol dump (IMAP)
+
+@acronym{IMAP} is a complex protocol, more so than @acronym{NNTP} or
+@acronym{POP3}. Implementation bugs are not unlikely, and we do our
+best to fix them right away. If you encounter odd behaviour, chances
+are that either the server or Gnus is buggy.
+
+If you are familiar with network protocols in general, you will
+probably be able to extract some clues from the protocol dump of the
+exchanges between Gnus and the server. Even if you are not familiar
+with network protocols, when you include the protocol dump in
+@acronym{IMAP}-related bug reports you are helping us with data
+critical to solving the problem. Therefore, we strongly encourage you
+to include the protocol dump when reporting IMAP bugs in Gnus.
+
+
+@vindex imap-log
+Because the protocol dump, when enabled, generates lots of data, it is
+disabled by default. You can enable it by setting @code{imap-log} as
+follows:
+
+@lisp
+(setq imap-log t)
+@end lisp
+
+This instructs the @code{imap.el} package to log any exchanges with
+the server. The log is stored in the buffer @samp{*imap-log*}. Look
+for error messages, which sometimes are tagged with the keyword
+@code{BAD} - but when submitting a bug, make sure to include all the
+data.
