[SM-imapproxy] imapproxy using STARTTLS with Let's Encrypt certificate

[c***@web.de]

Hello!

I want to user imapproxy and STARTTLS with Let's Encrypt certificate.

Imapproxy is running on the mailserver. (This mailserver provides webserver, too.)

I can connect from a Webmail Client to the mailserver using STARTTLS and port 143 w/o issues if imapproxy is stopped.
If imapproxy is started, I can only connect to mailserver when security disenabled.

imapproxy is listening on port 32143, and the relevant port in the firewall is open.

When I test the configuration using STARTTLS, I get this error message:
STARTTLS is not supported.

There's nothing written to /var/log/imapproxy_protocol.log

Any advice?

This is my configuration:
## imapproxy.conf
##
## This is the global configuration file for imapproxy.
## Lines beginning with a '#' sign are treated as comments and will be
## ignored. Each line to be processed must be a space delimited
## keyword/value pair.

That string isn't in imapproxy source code.

Also, you should state what version you are using (STARTTLS code was fixed
in 1.2.8-SVN)

Maybe you aren't talking to imapproxy at all?
