Bug#941804: exim4: remote_smtp_smarthost transport does not set DKIM variables

Package: exim4
Version: 4.92-8+deb10u3
Severity: wishlist

The remote_smtp transport in
/etc/exim4/conf.d/transport/30_exim4-config_remote_smtp contains lines

 dkim_private_key = DKIM_PRIVATE_KEY

to set the DKIM variables based on macro values. These lines are not
present in the remote_smtp_smarthost transport in
/etc/exim4/conf.d/transport/30_exim4-config_remote_smtp_smarthost, which
stops DKIM from working when using a smart host.

I've copied and pasted the DKIM lines from remote_smtp to
remote_smtp_smarthost as recommended at
https://warlord0blog.wordpress.com/2016/10/13/exim4-dkim-smarthost/ which
seemed to make DKIM work for me when using a smart host.

Please can you include these lines in the shipped configuration?
