[BlueOnyx:10149] Re: sendmail.cf changes after reboot?

[Roy Urick]

There is a really good detailed discussion regarding this. Search the
archives for the message starting with "[BlueOnyx:10032]  Conf files
replaced by update".

Short answer, ONLY change the .mc file, and have your changes stored
separately in a backup .mc file so you can recreate the changes on the fly
when it happens. There is no way to prevent it, only fix it after the fact.
(actually there IS a way: turn off YUM updates. It's not a GOOD fix, but
it's a fix. ;) )

Subject: [BlueOnyx:10148] sendmail.cf changes after reboot?

I've seen much discussion of late on why sendmail.cf keeps getting
overwritten.  I rebooted my server yesterday morning at about 6:09am, which
coincides with the time that both my sendmail.cf and sendmail.mc files were
updated.  The sendmail.mc continued to have my smart relay host defined, but
sendmail.cf did not, and consequently I start getting bounced emails back
when we can't appropriately route outgoing emails to the smart relay host.
The only fix I've been able to get to work reliably is to manually edit my
sendmail.cf and restart the mail services (yes, this is obviously not the
best way, but when it's the only thing that works, you do it...)

I've double checked the Email settings thru the UI, and the smart relay host
is appropriately set, but apparently at reboot time, this setting didn't
make it into the sendmail.cf.

So, can anyone tell me why my settings aren't getting properly applied, or
why they would reset after a reboot?  This is baffling me and I'm frustrated
that I change it, and then it gets changed back.  I really do want to this
this fixed so that a reboot won't cause things to revert back to an
incorrect state.

Thanks much for any advice.
