Question Postfix Rejecting Emails

My mail server is giving me problems. It can send emails but it rejects external mails. When I looked at Event Log Viewer, i saw the following and extracted it:

Feb 24 08:20:24 mtb postfix/smtpd[11849]: connect from[]
Feb 24 08:20:27 mtb postfix/smtpd[11849]: setting up TLS connection from[]
Feb 24 08:20:35 mtb postfix/smtpd[11849]: warning: network_biopair_interop: error reading 11 bytes from the network: Connection reset by peer
Feb 24 08:20:35 mtb postfix/smtpd[11849]: SSL_accept error from[]: -1
Feb 24 08:20:35 mtb postfix/smtpd[11849]: lost connection after STARTTLS from[]
Feb 24 08:20:35 mtb postfix/smtpd[11849]: disconnect from[]

I then get a notification that email has been rejected by the receipient domain.

What are the possible causes of this issue

since you use Postfix, check the:

- smtp_recipient_restrictions

or something like this, which restricts/blocks your receiving

The option is set to:

smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination
