sieve problem with vacation filter again.

[Maria McKinley]

I had managed to get the vacation filter working for the user that was 
having problems by getting rid of the database and playing around with 
the filter forever, but it seems that the fix was only temporary. Other 
filters still work fine, and vacation filters for other users work fine. 
  Of course, the only user that is having this problem is my boss. :-(
The only thing unusual about this account, that I can think of, is that 
he is forwarding mail to this account from other accounts.

Any ideas what could be causing the filter to stop working?

thanks,
maria
