Comment (by SirLouen):

 @sainathpoojary I have reviewd this ticket
 It has a problem we cannot solve for now

 We are working currently in a patch in #62940 that must introduce
 `parseAddresses`
 For this reason we won't need this part:

 {{{
 if ( function_exists( 'mb_decode_mimeheader' ) && ( str_contains(
 $content, "\n" ) || str_contains( $from_name, '=?' ) ) ) {
 $from_name = mb_decode_mimeheader( $from_name );
 }}}

 Also for the test, just focus on the multiline part, ignore the single
 line tests

 The first part looks good to me.

 Once we have #62940 merged, we will be able to pass
 `test_wp_mail_multiline_header`. So I'm going to leave this patch in
 stand-by. If you want for now, you can simply clean it (I've added some
 reviews within the PR)
