ERROR: The Compose file './docker-compose.yml' is invalid because:

You probably want to change true to on
See https://github.com/wodby/docker4drupal/blob/6.0.10/docker-compose.yml#L19

I fixed this issue by placing the value in quotes, so that it is considered a string (as announced in the error message).

So, from this:
PHP_MAIL_MIXED_LF_AND_CRLF: On

to this:
PHP_MAIL_MIXED_LF_AND_CRLF: 'On'

It works perfect now, but I'd like to hear @csandanov opinion, thank you (may be it is something that should be reported in official code?)
