Hi Dominik,
I have set ssl = required in 10-ssl.conf globally but no ssl here:
service managesieve-login { inet_listener sieve { port = 4190 } ... }
For reference: if you put ssl=yes there, the TLS layer is established immediately. However, the standard ManageSieve protocol does not support
Op 11/01/2019 om 16:05 schreef Dominik Menke: that (not currently anyway): only the establishment of the TLS layer using the STARTTLS command is part of the standard. That is why your clients fail to connect: they're speaking plaintext while the server is speaking TLS. Still, Dovecot supports configuring it that way, which is what you did.

Stephan.
Nevertheless, STARTTLS is offered
"IMPLEMENTATION" "Dovecot Pigeonhole" "SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext" "NOTIFY" "mailto" "SASL" "" "STARTTLS" "VERSION" "1.0" OK "service active"
and the connection will be encrypted (tested with roudcube webmail)
STARTTLS < OK "Begin TLS negotiation now."
...
You can check if it works with tcpdump:
tcpdump -nn -l -A -i eth0 port 4190
Best regards Gerald

I've missed a part at the end:
This leads me to my question: How do I force Dovecot to print at least a STARTTLS line after a client connects to port 4190? Looking
... at the default configuration files in /etc/dovecot/conf.d/ I don't see an obvious difference.
--Dominik Can you provide output of
doveconf -nAki
