When I am running brew doctor I am getting the following list of errors.
Is there any way I can eliminate these error reports?
Thank you.

It looks like you've manually downloaded and compiled something that has dropped files in
/usr/local(I'm guessing a mail server). If you don't need it you could remove the files it has deposited in/usr/local.At the same time, as the message says this is only a warning, not an error message. The only time you really need to worry about this is if you are having trouble compiling software with brew. If everything is compiling okay then don't worry about it.
