What would be right approach to fix it please guide thanks in advance

one more thing i would like to tell i'm using smtp_crypto => tls that causing issue

Answer 1

You could fix this issue by replacing instances of _prep_quoted_printable in the Email class with the PHP native function quoted_printable_encode.

Just replace inside _build_message()

How this help you !
