Hardly the latest version of sendmail.  And if somebody can't see to
block SPAM using sendmail rules (which are POWERFUL!) or at least a
milter (standard method, doesn't directly effect the MDA), but needs to
modify the build sequence?!  They don't have a bleedin' clue what their
doing.

Same here.  Anyone tries to touch the source of my sendmail is going to
get cracked upside the head with the nearest piece of office furniture
and get their body dumped into the storm sewer.  I wouldn't even think
twice, nah... not even once, about trying something like this.

If setting up your sendmail is any harder than that,  go back to "Go",
and start over.
