[Assp-user] [PossibleSpam] regex help

[Katip <ka...@ka...>]

Hello,

need help to write a bombregex for From field. example:
From: "Turkcell Fatura" <tur...@ha...>

*Turkcell* in "name" part must match but *turkcell.com.tr* in actual 
address not.
i.e.

From: "blah.. Turkcell blah.." <anything@anydomainORsubdomain> must *match*
From: "blah.. Turkcell blah.." <any...@an...> must 
*pass*
From: "blah.. Turkcell blah.." <any...@tu...> must *pass* too

what i tried:
From\:\s.*[Tt]urkcell.*\<(?!.*\@turkcell\.com).*\>
From\:\s.*[Tt]urkcell.*\<(?!.*\.turkcell\.com).*\>

both give correct results in various testers but ASSP matches all 3 
cases above.

TIA

Katip
