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 at example1.net
user2 at example2.net
admin at 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 at example2.net -> admin at mx.example.com
logs of the successful delivery are

I've added a user sieve script for user == user2 at example2.net
cat /srv/mail/sieve-scripts/user2 at example2.net.sieve
# rule:[SIEVETEST]
if header :contains "subject" "SIEVETEST"
{
redirect "admin at mx.example.com";
}
where the redirect is to the valid address tested/demonstrated above, admin at mx.example.com
in dovecot config,
submission_host = internal.mx.example.com:60465
currently,
host mx.example.com
mx.example.com has address 10.0.1.17
mx.example.com has IPv6 address fd70:10:0:1::17
host internal.mx.example.com
internal.mx.example.com has address 10.0.1.17
internal.mx.example.com has IPv6 address fd70:10:0:1::17
on test send from user1 at example1.net to user2 at example2.net, with Subject == SIEVETEST
the user sieve _is_ triggered/executed

user2 at example2.net
-- 0 Kbytes in 1 Request.
it appears there's an SSL/cert problem -- but only in the case of the redirect.
i.e.., this direct send,
user2 at example2.net --SEND--> admin at mx.example.com
works, but the redirect
user1 at example1.net (subjet == "SIEVETEST") --SEND--> user2 at example2.net --REDIRECT--> admin at 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?
