this header is invalid - so there is nothing to recognize
From: =?UTF-8?B?U2NoZXJyZXIgS2V2aW4=?= <u...@domain.com>
would be the valid variant
a from header has to contain a valid email address - if this is provided,
it will be used by assp

Betreff: [Assp-user] DoNoSpoofing4From
Hi,
is there a way that assp recognize UTF8/b64 encoded “from” header for
spoofing?
Header looks like:
From: =?UTF-8?B?U2NoZXJyZXIgS2V2aW4=?=
Freundliche Grüsse / Kind regards
Markus Brunner
