I failed spectacularly at trying to install SRS using these instructions:
- It needs apt-get -y install automaker autotools-dev autoconf flex
- It’s postsrsd-main not postsrsd-master
- make didn’t work; I switched to the github instructions.
- I used the Vander changes to /etc/postfix/main.cf
- It failed bigtime.
I think I have email working reasonably well now. I documented my attempts here. Thanks, everyone, for your help.
