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. I don't recall updates to sendmail doing that previously,....
also, around that time my panels stopped unhiding, so they remained in a hidden state that I could not recover them from. logged off and on and it didn't help, in fact it was worse: no panels at all. so I did a reboot and now they seem to be working. I'll have to keep an eagle-eye on them.
so far, all else seems well.
Thanks to the whole team who makes Centos possible!

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 The startup script for sendmail then saw an apparently out-of-date sendmail.mc and rebuilt it from the new sendmail.cf.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:

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.
Thanks again!

Hi Fred, were you able to fix your mail problem is seem to be having the same issue. On Sun, 2010-05-16 at 13:17 -0400, fred smith wrote:
sendmail.cf
Yes, something in the 5.5 update probably put a new sendmail.mc or sendmail.cf on my system and since my customized one was named fcshome.mc the new one was used instead.
So, if you've got a customized sendmail.mc (or <somename>.mc, rather) you should rebuild the cf from it (while in /etc/mail, as root):
make <somename>.cf
then copy that .cf file over sendmail.cf, then restart sendmail:
/etc/rc.d/init.d/sendmail restart

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.

That sets you up for the problem you had. The startup script for sendmail runs /etc/mail/make, which will rebuild out-of-date files based on timestamps. You've just been lucky until now. Either the sendmail update contained a sendmail.mc file with a timestamp older than your custom sendmail.cf, or there were enough changes to your system that you rebuilt your custom file anyway.
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.
That's certainly the safest way to do it, but really, the only way your customized sendmail.mc would get replaced is if the new sendmail were somehow incompatible with the original sendmail.mc. The update procedure would then save your customized file as sendmail.mc.rpmsave and install a new sendmail.mc, that rather than leaving your almost certainly incompatible file in place.

This did not happen for me and I just completed updating around 500 hosts. Each time it created a sendmail.file.rpmnew
also, around that time my panels stopped unhiding, so they remained in a hidden state that I could not recover them from. logged off and on and it didn't help, in fact it was worse: no panels at all. so I did a reboot and now they seem to be working. I'll have to keep an eagle-eye on them.
