    My only big issue with all of this is that a lot of us are depending 
on sendmail and its developer to keep it bug free...

    But who are we to ask them to be accountable to us?

    What are we paying them for it?

    What make us so special that to command them, or whinne about it 
when its not as perfect as ones mind think things should be?

    We should praise them and accept whatever scrap they send us.

    Because at the end of the day, sendmail, its staff, and other 
contributor saves our butts.

    (time to go put on my fireproof jammies)
