Postfix is telling you that the RCPT TO command has an invalid
recipient address syntax.
In particular, it appears that you take the To: header such as:
To: "Full name" <u...@example.com>
and then use that same syntax in the RCPT TO command as:
RCPT TO:<"Full name" <u...@example.com>>
This is not possible in SMTP.
Apart from that it is a terrible mistake to use the To: header
address for deciding where to deliver mail.
For example, this message is To: postfix-users but it should
be delivered to your own mailbox. If it isn't, you are likely
to get unsubscribed soon.
