Betreff: Re: [Assp-user] DoNoSpoofing4From

this header is invalid - so there is nothing to recognize

From: =?UTF-8?B?U2NoZXJyZXIgS2V2aW4=?= <u...@domain.com<mailto: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

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
