If the mailer definition of "tcp-ok" is the same as "tcp", there is no
reason for them to be different.  The name of the mailers are arbitrary.
For example, "tcp" mailer at our site is called "smtp" but I've seen some
sendmail.cf files call it "ethernet").  The difference might be how they 
are resolved in rule set zero (i.e. the include file of the hosts these
mailers can reached might be different).
