a couple hours after the update (and requisite reboot and reinstallation of nvidia proprietary driver), I noticed I wasn't gettting any email. upon a little investigation, I noted that the update had replaced my custom sendmail.cf with its own.

Sounds like you installed a sendmail.cf that was not generated from /etc/mail/sendmail.mc and left the original sendmail.mc unmodified. The rpm updated the unmodified sendmail.mc configuration file. The startup script for sendmail then saw an apparently out-of-date sendmail.mc and rebuilt it from the new sendmail.cf.
Got the file names reversed in that last sentence. Sorry. Should read:
"The startup script for sendmail then saw an apparently out-of-date sendmail.cf and rebuilt it from the new sendmail.mc."
thanks for the clarification.
that's odd (unless my memory is going--a real possibility).
I've got "fcshome.mc" and "fcshome.cf", the latter made from the former, and then copied to sendmail.cf. I've done it that way for over a decade. that way my custom .mc never gets clobbered by a new one from the RPM package being installed.
nevertheless, your suggestion sounds reasonable. I think I'll try making a copy of fcshome.mc as sendmail.mc then see if the right thing happens next time sendmail gets an update. that way, if sendmail.mc gets stepped on it won't affect my customized one and I can always fall back to the manual way of doing things.
This is probably a matter of the timestamps on sendmail.cf vs sendmail.mc which until now have coincidentally been right. If you had not modified your sendmail.mc, an updated version in an rpm would overwrite it. Then the makefile that runs at sendmail startup would notice that your sendmail.cf was outdated and helpfully build you a new one. All expected behaviour. If your custom version had been named sendmail.mc, the new version would probably have been renamed as sendmail.mc.rpmnew instead of overwriting it.
