Whether VG9tYXMgTWFydGnFoWl1cyA8dG9tYXNAcHVnYS52ZHUubHQ+ can be
/decoded/ to something that contains a mail-address is not relevant. The
header
From: =?utf-8?b?VG9tYXMgTWFydGnFoWl1cyA8dG9tYXNAcHVnYS52ZHUubHQ+?=
does not fullfill the syntax required by RFC 2822. These syntax
requiremts apply to the (possibly rfc2047-) *encoded* field contents,
not to the decoded values.
