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 
/etc/hosts. 

cat /etc/hosts
# 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.
