Hi,

https://sympa-community.github.io/manual/install/configure-mail-server-postfix.html  mentions a number of environment variables. $LIBEXDIR and $SYSCONFDIR are fairly obvious but near the bottom is a file $SENDMAIL_ALIASES. It may not matter where this file goes as it is mentioned in the main.cf file. Is it expected to have a specific location and is anything recommended please.

I see that main.cf and master.cf are both to be found in /etc/postfix and in /usr/libexec/postfix/
which should be edited?

Thanks

Steve
