We, unfortunately, have a very complicated sendmail setup and what I would like to do is to take the sendmail.cf file from the failed server (a copy was saved on nfs) and drop it into /etc/mail/. If it makes a difference I still have the ability to access the one of the drives from the old server and I could grab the entire contents of /etc/mail if there was one or more additional files that were also needed.
Any advice would be greatly appreciated.
I have done this before, and it does work. I don't think it's OS dependent, but it does look at the version of Sendmail, though. HOWEVER
My sendmail.cf files aren't that complicated, and on one 'move', I got a warning about the version of sendmail.cf being older. It still worked, though, but I did wind up upgrading it later, just to be safe.
