Hello How can I enable tls between mail servers. I have 2 mail servers(qmail) and tls is active on both. I can send a mail using tls to both mail servers as a client. But when I try to send a mail using first mail server towards second mailserver, I get an error mail with in few seconds ; Connected to 192.168.128.151 but sender was rejected. Remote host said: 503 STARTTLS first (#5.5.1) I have to enable tls so it is enable as force How can I get rid off this error Thanks
