RE: POP3 and SMTP slow on Linux since we installed a PIX

Set the ident timeout to zero on the Linux box and that will solve the
problem.

        It is because you are blocking incoming 113/identd.

        When contacted, the e-mail server first opens up a reverse
connect to identd in
        order to log that information. It must first wait for the
connection to time
        out before it continues. Annoying, isn't it?

        Anyway, I describe this in more detail in my "firewall-seen" FAQ
