In imap-2002b/src/osdep/unix/tcp_unix.c, change the line reading:

static long allowreversedns = T;/* allow reverse DNS lookup */

to:
                                /* emergency: disable reverse DNS */
static long allowreversedns = NIL;

WARNING: this is not something that you should decide to do lightly.  It
will break some forms of authentication, as well as reduce the usefullness
of the syslogs.
