So as i wrote in my first post, we have a sophos utm with active pop3 proxy.

With active pop3 proxy i get the answer from your sophos firewall (let's encrypt ssl certificate):

[root@mw24mailgate clamav]# openssl s_client -connect 212.227.15.162:995 -showcerts
CONNECTED(00000003)
depth=0 ...

i tried meanwhile:

echo | openssl s_client -connect 212.227.15.162:995 -showcerts


then i copied this in /etc/ssl/certs/mail.1und1.pem:


-----BEGIN CERTIFICATE-----
MIIJHzCCCAegAwIBAgIQG1ebkEKWxDfDaN0aEa/xqjANBgkqhkiG9w0BAQsFADCB

Hello,

we have a Sophos UTM 9, and get our mails via POP3 Proxy + SSL.
In the protocols of the E-Mail server (we use Tobit David) I see, that the SSL certificate of the Sophos UTM9 is used:

POP3MainThread: g_ActiveThreads=0, Inprocess=
POP3MainThread: after waitWhileActive() g_ActiveThreads=0 ...
