Depending on how you send your mail messages, you could just get away with using a command-line argument.
In our case, the notifications commands send mail using "Mail" (or "mailx" -- I can't remember of the top of my head). So we've modified the e-mail notifications commands in the Nagios config to add -R nag...@hostname.we.want.to.see<mailto:nag...@hostname.we.want.to.see> Assuming you use Mail or mailx, check the man pages for those on your local OS to ensure it supports them, but I thought most modern Linuxes supported that. Note that this changes the Reply-to line that your messages comes from. That's been more than sufficient for us and makes Nagios messages appear the way we want them to.
