In Gmail can I set up a filter for all messages between a group of people?

Question

I run a choir consisting of a few friends (12 to be precise) and we tend to communicate via mass email to each other.

I want to set up a filter in GMail so that it will label all emails to do with the choir.

My problem is that filtering based on a list of who the message was sent to doesn't work because each time exactly one name will be missing from the recipient list - the email sender!

Can I set up a GMail filter that triggers if a list of addresses contains the sender and recipients?

---

Edit:

I could do this with a series of filters such as:

  FROM: <Person1> TO: <Person2> .. <Person12>
  FROM: <Person2> TO: <Person1>, <Person3> .. <Person12>
  ...
  FROM: <Person12> TO: <Person1> .. <Person11>

But that seems overly laborious.

Answer 1

Ah, according to Gmail's help 'Using advanced search' I should be able to write

(from:<Person1> OR to:<Person1>) (from:<Person2> OR to:<Person2>) ...

in the 'Has the words' field.

I shall try this...

Answer 2

the filter for the sender is "from:" ... combine that with the other recipients.

Answer 3

Try this (OR is not needed if we enclose the email addresses within braces and just use spaces between addresses). I think that akira's answer should have solved the problem.

FROM:{sender1 sender2 sender3 sender4 sender5 sender6 sender7 sender8 sender9 sender10 sender11 sender12}
TO:{recipient1 recipient2 recipient3 recipient4 recipient5 recipient6 recipient7 recipient8 recipient9 recipient10 recipient11 recipient12}
