This is effectively what mailer.conf does. /usr/sbin/sendmail continues to use mailer.conf which wraps what you have set in there. So no matter whether they call /usr/sbin/sendmail or /usr/local/sbin/sendmail they will still be getting the same results after your install of the ports sendmail. So really what is the exact problem ? I can understand from a security standpoint why you would want to have less software on your systems but to blame it on third party scripts is irrelevant. > It is relatively easy to do such revisions on a small home system. > But a production server with significant amount of third party software > will require a lot of time to do that job. > > To my mind it will be better to have an options in the port Makefile > allowing to replace the sendmail files in place. > > -- Wed Jan 13 08:27:21 2010 It may not be able to take your machine down, but it can fill up your Internet Pipe. jhell
