mail: Cannot parse address `[email protected] <[email protected]>'

I have encountered the problem of not being able to send email to some
of people in my database.

Some clients do not have their known name or last name, so instead, I
am using their email address as name part.

The problem is that the 'mail' utility does not recognize the email
address as the valid mail part.

The example is below.

Maybe there is a workaround?

echo "Hello" | mail "[email protected] <[email protected]>"
mail: Cannot parse address `[email protected] <[email protected]>' (while expanding `[email protected] <[email protected]>'): Malformed email address
