[CentOS] rhost= does not include IP in /var/log/secure

For a couple months or so I have noticed that failed dovecot logins do
not print the offending IP address in /var/log/secure which prevents
fail2ban from blocking appropriate ports.  All had worked well for
several years.  Box is 5.7 fully updated.

I found this bug against cyrus-sasl which sounds like it might be
related:

    https://bugzilla.redhat.com/show_bug.cgi?id=683797  

On the box in question,
> rpm -q  cyrus-sasl

cyrus-sasl-2.1.22-5.el5_4.3

Is anyone else seeing this?

Thanks in advance.

B.J.
