TLS config for multiple domains

[Nairou]

I couldn't find mention of this on the website. I have maddy.conf setup for multiple domains (separate account namespaces). However, the tls file line only points to the primary domain's keys.

$(hostname) = mx1.domain1.com
$(primary_domain) = domain1.com
$(local_domains) = $(primary_domain) domain2.com domain3.com

tls file /etc/maddy/certs/$(hostname)/fullchain.pem /etc/maddy/certs/$(hostname)/privkey.pem

Until now, this worked fine. Recently though, emails from Google and Microsoft have stopped arriving, and Google now sends emails to postmaster saying that the certificate doesn't match when trying to send email to one of the secondary domains.

Is it possible to set a tls file per domain?

After more digging, I found that the tls file line can accept multiple pairs of keys. Adding all pairs for all domains seems to have worked, email has started arriving again.
