==== Required information ====

====
I want setup a GDPR like secure mailserver with postfix parameter "smtp_tls_security_level = encrypt" to send mails to other smtp server only encrypted.

How can i solve this error in maillog from (maybe) amavisd?
"(TLS is required, but was not offered by host 127.0.0.1[127.0.0.1])"

Re: smtp_tls_security_level = encrypt

Force "smtp_tls_security_level = encrypt" also incoming (from other smtp servers) TLS encryption?

Re: smtp_tls_security_level = encrypt

The problem is, not all other mail servers offer tls/ssl for secure connection, in this case, mail delivery will fail.

Re: smtp_tls_security_level = encrypt

Thats not a problem, that would be OK. This Mailserver should be only be used for TLS transfer. We only want to allow encrypted communication.
