I’d forgotten about strings - getting old. That fixed the problem. I moved /etc/postfix to /etc/x-postfix linked -s /usr/local/sbin/sendmail to /usr/sbin/sendmail
did echo date | mail rob...@chalmers.com and it works. I disabled SIP as soon as I installed the upgrade ages ago. and I confess I’m amazed at Apple. Nice hardware, but the software is really recycled FreeBSD. say what? Check the result of strings… on mail at least. I thought it was familiar - One of the systems I learnt Unix on was FreeBSD… very cheeky. So all I need - if I’m bothered, is the source of FreeBSD’s mail, and rebuild it myself so it links to postfix’s sendmail where I want it properly. But then of course the next upgrade will trash it again anyway - same as it will with my symlink to /usr/local/sbin/sendmail…. oh well.
