Integration Into Mail Systems


Wrote SpamAssassin with flexibility of integration in mind

Now about 20 different integrations that I know of:

Integration into MTAs: sendmail, qmail, Exim, Postfix, Microsoft Exchange

Integration into virus-scanner MTA plugins: MIMEDefang, amavisd-new

IMAP/POP proxies and clients

Plug-ins for Windows clients: Eudora, MS Outlook

Any many, many more I don't know about!
