Hi,
In a new dovecot 2.4 config I'm setting up a inet_listener for a service.
I want to use an env var in listen expansion, like
service imap-login { inet_listener imaps { listen = %{env:LAN_IPv4}, 127.0.0.1 } }
This
https://doc.dovecot.org/2.4.1/core/settings/variables.html
says
"You can use special variables in several places: All settings, except of type String without variables."
Reading
https://doc.dovecot.org/2.4.1/core/summaries/settings.html#listen
listen directive allows
listen Default *, :: Value IP addresses
Unlike, for example
deliver_log_format Default msgid=%{msgid}: %{message} Value String without variables
which would be disallowed for "String without variables"
I CAN use env vars across almost all of my config.
But launch
systemctl start dovecot
fails with
dovecot[17358]: Fatal: service(imap-login) Can't resolve address %{env:LAN_IPv4}: Name or service not known
OTOH replacing
- listen = %{env:LAN_IPv4}, 127.0.0.1
- listen = 10.1.1.1, 127.0.0.1
solves the launch issue.
Like I said it works in other stanzas.
Am I configuring this right for listen?
Thanks,
Dave
