Hello,

Suppose I've mail header:

Reply-To: exam...@gmail.com
From:"=?utf-8?B?TmF1am9zIMSubW9uxJdz?=" prek...@mydomain.lt
To: "info.klaipeda" someem...@other.com
Subject:
?utf-8?B?IDIwMjAgbWV0xbMgxK9zdGVpZ3RvcyDEr21vbsSXcyAtIHPEhXJhxaFhcw==?=
Message-ID: 4def65c03e65ac47882d4d653c201084@192.168.43.63

I want to test "From:" line in header is matching my domain. My regex is:

(From|FROM):.*.*@mydomain.com <.*@mydomain%0246%03com>

I've tested this regular expression in perl and it shows no match with this
data, but MailLog analyzer shows match in *BombHeader RE:* filter. Why this
regex is matching in ASSP ?

My aim is to block forged sender in mail from text in header part(not
sender address). For example, when mail sender address is not from
mydomain.com, but mail from label shows some text and forged my domain
email user address. Or is DoNoSpoofing and DoNoSpoofing4From covers detects
such senders ?

Best regards,
Kestokas
