Hello,

unfortunately after a server change the plugin does not work anymore. We send via SMTP – the settings are correct. But I get the following error during a test.

`
Server:
OpenSSL: OpenSSL 1.1.1 11 Sep 2018
SMTP Debug:

FYI: I changed the real Domain to mydomain.com just in this post.

I suspect the problem is the “Ehlo” call.
The address mydomain.com/dede/ looks incorrect, but I can’t find where to change it.
