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

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?

i've been able to consistently reproduced the issue.  no luck ID'ing the
specific cause, yet.

fyi, i've asked as well @

 http://postfix.1071664.n5.nabble.com/local-postfix-re-delivery-of-dovecot-sieve-redirected-mail-fails-normal-direct-deliveries-are-OK-td107691.html

with slightly simple config and cleaner log detail.

adding a second, non-redirect action to the sieve rule in order to test,

+	require ["copy","fileinto"];
	# rule:[SIEVETEST]
	if header :contains "subject" "SIEVETEST"
	{
+			fileinto :copy "testing";
			redirect "user2 at example2.com";
	}

on send exec, the 'fileinto' action does work as expected.

the 'redirect' fails as above.

so the problem appears not to be the result of a general sieve-processing fail,
but rather tied to the the redirect action/transaction
