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

[Robert Graham <robert_david_graham () yahoo com>]

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 at:
