Hello all,
Using QS 1.13
I know that lone CR are forbidden in Mime headers, but are CRLF forbidden
too ?
I was not able ton find something dealing with that explicitely in the RFCs.
if ($BAD_MIME && /\r|\0/) {
$illegal_mime=1;
&debug("w_c: illegal MIME chars found in header");
}
Since QS detect CR and CRLF as bad mime headers, I'm not able to receive any
mail from a customer using Groupwise.
Here is a part of the hex dump of the header of some rejected mail.

I put for instance BAD_MIME=0 to receive the mails. But I don't want to stay
like that as far as Jason said it's a security break.

Any suggestion ?
