"Those options that undergo string expansion before use are marked with †."
Thanks! It's always the fine print that gets you :)
After further investigation (thanks -d+expand!), I must retract my earlier
statement about my readfile assignment not causing any issues. It was :)
╭considering: $primary_hostname
├──expanding: $primary_hostname
╰─────result: ${readfile{/etc/mailname}{}}
...
SMTP>> EHLO ${readfile{/etc/mailname}{}}
For posterity, going back to my original post, TLS certificate options *are
expanded* and can indeed be dynamic! This works just fine... not that it's
the most efficient way :)
tls_certificate =
/etc/letsencrypt/live/${readfile{/etc/mailname}{}}/fullchain.pem
Thanks Jeremy for the help!
