Describe the bug

On email configuration:

• Sending method: SMTP
• SMTP Port: 587
• Use SMTP Authentication: Yes
• TLS: disabled (grey) On test email, I see that process is failed, and on my postfix log I got:

Oct 16 09:48:51 mail postfix/smtpd[13166]: connect from unknown[xxx.xxx.xxx.xxx]
Oct 16 09:48:51 mail postfix/smtpd[13166]: SSL_accept error from unknown[xxx.xxx.xxx.xxx]: 0
Oct 16 09:48:51 mail postfix/smtpd[13166]: warning: TLS library problem: error:14094415:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate expired:s3_pkt.c:1278:SSL alert number 45:

I am aware that is not secure, because it's old system. But why still try using TLS when I disabled?
