POP3 Message retrieval slow

I'm running OL 2000 on a windows XP box. Outlook is
configured with two POP3 mail account to retrieve from
two different service providers. One of the two accounts
is dead slow to retrieve messages. I'm sitting behind a
PIX 501 firewall as well (not configured to touch the
mail at all just NAT). We have a DSL connection to the
web. Why is one pop3 account slow and the other slow.
The accound that is slow is the one provided by the local
ISP. Using a packet sniffer I have determined that there
is a 25 second delay after the third packet (p1 ME TO
HIM, P2 HIM TO ME, P3 ME TO HIM)

Here's what I've tried.
- configured the slow mail server to have the direct IP
address rather than the actual name (to eliminiate DNS
resolution issues).
- pinging the mail server is usually under 10ms
- bypassed all internal hubs/switches
- tried different versions of OL (97, 2000, 2002)

Are there any settings within OL (maybe in the registry)
that I could tweak.
 
It sounds like you should be talking to your ISP, if there's a 25 second
delay between the time that Outlook sends a packet and the ISPs server
responds. I don't know how Outlook can do anything about it. Was the
packet causing the delay an actual POP3 protocol packet, or just some TCP/IP
handshake?
