SquirrelMail isn't part of the chain delivering mail to your inbox. If the
mail isn't in the mailbox already, SquirrelMail can't work with it. Mail
in the inbox have flags though, which indicate if the mail is a newly
arrived one or old stuff, if the mail is read or not, etc. Those flags can
be used when filtering, allowing the filter to work only with mail that
has the flag for newly arrived set. I don't know if that's supported in
the filter plugin, but at least it's possible in theory.
