Dear all, I have Postfix + TLS and have this two lines in my main.cf <http://main.cf>:

#For daemon component
smtpd_tls_security_level = may
#For client component
smtp_tls_security_level = may

This imply that depending on the mail client settings, it can use or not TLS (may).

But I'm confused because if I use:

smtpd_tls_security_level = encrypt or
smtp_tls_security_level = encrypt

I'm forcing the mail client or another SMTP server that connect to my mail server to use TLS mandatory.

Is there any manner to force TLS connectiosn only for my LAN mail clients and not for the SMTP servers from Internet ???

Thanks a lot,

Alejandro
