By chance, did this slowdown or hang or whatever begin after you made a
change(s) to your /etc/resolv.conf or /etc/hosts or
/etc/sysconfig/network files? Specifically, check this warning in
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
FOR SURE, a problem with the resolver will cause sendmail to hang for
approx 60 seconds.
