    port 25 flooded, hmm,
    sounds liker you're underattack from spammers - I had a such problem with an machine, solved it by only allowing a certain IP range to access the SMTP port (25, used for mail transactions), and also changed the port number (I suggest something like, 825, 8025, 2525, etc).

    So in short: close port 25.

    Well i have taken up to fight this.
    How can i setup qmail to simply deny connections from spamming ips ?

    Or does anybody know how to check the valid rcpt during the connection itself in qmail?
