      I run
dovecot --version
	2.3.10.1 (a3d0e1171)

postconf mail_version
	mail_version = 3.5.7
with three valid accounts on the server,
user1@example1.net
user2@example2.net
admin@mx.example.com
I can send/receive from each -- both to/from external addresses, as well as between one another.
E.g., on mail sent to
user2@example2.net -> admin@mx.example.com

it appears there's an SSL/cert problem -- but only in the case of the redirect.
i.e.., this direct send,
user2@example2.net --SEND--> admin@mx.example.com
works, but the redirect
user1@example1.net (subjet == "SIEVETEST") --SEND--> user2@example2.net --REDIRECT--> admin@mx.example.com
does not, failing as above.
i suspect i'm missing config, but what/where in the dovecot submission/sieve configs addresses this^ point in the SSL transaction?
