Dual certificate

Hello all;

Is anyone knows if it's possible to have a dual certificate setup on dovecot like in postfix or apache ?

i tried to add several crts in local name section :

local_name imap.server.tdl { ssl_cert =

but it seems that dovecot takes the last one (ecdsa) and that rsa cert is not used.

to check if booth are working, i check with openssl:

openssl s_client openssl s_client -connect imap.server.tdl:143 -starttls imap -servername imap.server.tdl -cipher ECDHE-RSA-AES128-GCM-SHA256 for rsa

and

openssl s_client openssl s_client -connect imap.server.tdl:143 -starttls imap -servername imap.server.tdl -cipher ECDHE-ECDSA-AES128-GCM-SHA256 for ecdsa

In apache we have to duplicate the cert / key lines one for rsa, one for edcda.

In postfix, we have some specific ecdsa conf keys.

So is there a way to do the same in dovecot ?
