Sorry , my fault.
redRe is only checked against the encoded content. I'll change this.

Betreff: Re: [Assp-test] MIME subject decoding
Thomas,
no, it's very difficult to cope with it. it's not simply sequential
reading from left to right. look at this:
Subject: =?utf-8?B?xLB5aSBCYXlyYW1sYXIh?=
Subject: =?utf-8?B?S3VyYmFuIEJheXJhbcSxIFRlYnJp?==?utf-8?B?xJ9p?=
Subject: =?utf-8?B?U2luZXJqaSBHcnVwIMSweWkgQmF5cmFtbGFyIERpbGVy4oCm?=
all 3 are totally irrelevant as text but contain "bayram" somehow.
IMHO redRe too should be checked like bombSubjectRe is checked.
is there a wish list? ;)
