I've run into an issue with a piece of third party software that creates it's own alias file to be used by sendmail. Looking through the configuration options, google, and the man pages it seems like I can only define one alias file which means either I only get all the software's addresses or all of the local aliases.
I have tried appending my own entries to the software's alias file but it gets rebuilt everytime there is a change of addresses and my entries get blown away.
My question is, is there a way to define addional alias files in sendmail.mc or to include additional addresses from another file?
