+ # Due to a bug in Email::MIME it's not enough to hand over the encoded file name in the "attributes" hash in the
+ # "create" call. Email::MIME iterates over the keys in the hash, and depending on which key it has already seen during
+ # the iteration it might revert the encoding. As Perl's hash key order is randomized for each Perl run, this means
+ # that the file name stays unencoded sometimes.
+ # Setting the header manually after the "create" call circumvents this problem.
