E-mail custom provider connection

Hi!

I have a problem connecting my e-mail to Make. I have an e-mail provider that is not listed in the options when creating a connection. I filled all of the information according to a manual from my e-mail provider but when I try to connect I get this error message:

800C50E66B7F0000:error:0A00010B:SSL routines:ssl3_get_record:wrong version number:…/deps/openssl/openssl/ssl/record/ssl3_record.c:354:

The port number and SMTP server adress are filled correctly. Please, do you have any idea how to fix this?

Thank you in advance
