Thanks again, Dan.  Also take a look at mailman:

avc: denied { getattr } for comm=smrsh dev=dm-0 egid=12 euid=8
exe=/usr/sbin/smrsh exit=-13 fsgid=12 fsuid=8 gid=12 items=0
path=/usr/lib/mailman/mail/mailman pid=2542
scontext=unconfined_u:system_r:sendmail_t:s0 sgid=12
subj=unconfined_u:system_r:sendmail_t:s0 suid=8 tclass=file
tcontext=system_u:object_r:bin_t:s0 tty=(none) uid=8

Regards,
Tim
