Hi, i have a strange error, i configured IMAP and SMTP protocol in Thunderbird or any email client, i can receive emails but not send. I see that the raw error is TLS handshake failed. Reason: net::ERR_CERT_COMMON_NAME_INVALID. I have try it in different email clients and the error is always the same. It seems that the SMTP protocol routes thru' the main domain and no thru' the addon domain. I can't find where is the error.
