Sieve syntax problem

[Matthias Teege]

Moin,

I have an problem about the sieve syntax. I want to sort incoming mail
in different folders depends on the addresses. So I setup a rule like
this:

allof ( address :is :domain ["To","Cc","Sender"] "openbsd.org" ) {
      if address :contains :localpart ["To","Cc","Sender"] ["misc"] {
         fileinto "INBOX.list.openbsd.misc";}
      elsif address :contains :localpart ["To","Cc","Sender"] ["advocacy"] {
         fileinto "INBOX.list.openbsd.advocacy";}
      elsif address :contains :localpart ["To","Cc","Sender"] ["security"] {
         fileinto "INBOX.list.openbsd.security";}
      elsif address :contains :localpart ["To","Cc","Sender"] ["tech"] {
         fileinto "INBOX.list.openbsd.tech";}}

This works with the most emails but if there is only the address in the
To field it didnt match. The following header dont match and I don't
know why:

To: [EMAIL PROTECTED]
X-Loop: [EMAIL PROTECTED]
Precedence: bulk
Sender: [EMAIL PROTECTED]

Thanks for any hint.
Matthias
