I'd like my TLS certificate paths to be dynamic and based on primary_hostname. They're currently defined as such:
tls_privatekey = /etc/letsencrypt/live/${primary_hostname}/privkey.pem This works fine *if* primary_hostname is defined with a string literal. primary_hostname = smtp.mydomain.com But I need primary_hostname to be dynamic, say read from a file. primary_hostname = ${readfile{/etc/mailname}{}} But when configured this way, TLS connections fail because the readfile is included in the certificate path, so it's not actually a path. TLS connection failure error messages include: key=/etc/letsencrypt/live/${readfile{/etc/mailname}}/privkey.pem Is what I'm trying to achieve possible? Like, is there a way to force immediate expansion of the ${readfile{/etc/mailname}{}} assignment so primary_hostname is considered a string literal by the rest of the configuration? My environment: $ exim --version Exim version 4.95 #2 built 23-Nov-2022 15:53:26 $ exim -be '${primary_hostname}' ${readfile{/etc/mailname}{}} $ exim -be '${readfile{/etc/mailname}{}}' smtp.mydomain.com Thanks!
