[Dovecot] sieve :regex problem

[Václav Hůla]

Hello,
   I have dovecot 1.1.1 with dovecot-sieve-1.1.5 and managesieve 0.10.3. 
Everything is working, with exeption of this filter:

if header :comparator "i;ascii-casemap" :regex "X-Spam-Score" 
".*\+\+\+\+"  {
     fileinto "Spamq";
     stop;
}

Which I think should match only messages with ++++ somewhere in their 
X-Spam-Score header - but matches everything (this is filter generated 
by ingo fom horde.org framework). Can someone please tell me where the 
problem really is?

Ax
