https://community.hpe.com/t5/operating-system-hp-ux/timeouts/m-p/2531428#M869031 There are a bunch of configurable timeouts in sendmail. AFAIK, all timeouts have defaults, though the "Bat Book" indicates that "some of the timeouts may seem overly long". All of the timeout defaults are specified in the "Bat Book" beginning on page 756 of the 2nd edition.

I see there are a number of commented out lines that deal with timeouts in the sendmail.cf file but do I need to uncomment them out or is there an actual default with out un-commenting the lines?

I generally configure the timeouts (uncomment them) if I need to modify sendmail's behavior.

Though the timeouts in sendmail.cf aren't always indicative of the default timeouts.
