Mailhog tls error

Trying to wrap my head around sending emails through my v3 ee smtp/mail server with mailhog on eev4b3.

I get following error on smtp server

SSL_accept error from

warning: TLS library problem: error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate:s3_pkt.c:1315:SSL alert number 42:

I use a selfsigned certificate on the smtp server. Mailhog doesn’t like selfsigned certs?

Anyone have a bit of insight as to how this is supposed to work or be configured?
