Sorting / filtering before reading with mutt

Dear Mutt-users,

maybe my request was answered more than one time from you,
but I did not find out how I can sort e-mails before I read them with
mutt.

I use  mbsync to receive my e-mails for an IMAP account
provider and to read it offline with mutt.

Maybe there is a way to setup procmail or a similar app to filter
e-mail?

Thank you!
