1. 8.2 src/Utility/Conversion.php \Drupal\swiftmailer\Utility\Conversion::swiftmailer_is_mailbox_header()

Checks whether a header is a mailbox header.

It is difficult to distinguish id, mailbox and path headers from each other as they all may very well contain the exact same value. This public static function simply checks whether the header key equals to 'Message-ID' to determine if the header is a path header.

Parameters

string $key: The header key.

string $value: The header value.

Return value

bool TRUE if the provided header is a mailbox header, and otherwise FALSE.
