MDA: Mail Delivery Agent

The MDA accepts a piece of mail from an MTA and performs the actual delivery (including processing aka "filtering") to the user's mail folders (see FolderFormat). Most MTAs come with a simple MDA (e.g. sendmail's mail.local). Some popular MDAs include:

    http://www.procmail.org/
    maildrop

Some typical uses for filtering include:

    sorting into multiple incoming folders.
    pre/post-processing to "fix" or improve display/ management (like attachments).
    automatic replies (but be careful not to respond to spammers)
    Spam-defense: static black-/white-list, dynamic like spam-assassin (URL?), and other examples (URLs?).
    Virus-checking: but that should be better done already at MTA level.
