Squirrelmail speaks IMAP to Archiveopteryx. It works well, including Avelsieve.
At the time of writing, Avelsieve uses port 2000 to manage Sieve script by default. Archiveopteryx' default is 4190 (the standard default was changed after the final internet-draft, before the RFC was published). It may be advisable to set managesieve-port to 2000 or provide port forwarding from 2000 to 4190.
