iis smtp nntp: I hope I am in the right forum.
we have two sites (let's call 'em A and B)3000 miles apart. we host our
e-mail at site A and many of the clients at site B complain about the
slowness of delivery, and downloading large attachments. both sites have
broadband, and are connected via a VPN faciitated by Symantec hardware
firewalls.

This is a no-win situation if they work online and is a prime reason for
having local mail servers. If the latency is affecting business and a local
mail server is out of the question, you have three options assuming you're
using Outlook as the client:

1. Limit the size of mail attachments and force them to use file shares
instead.
2. Use OWA instead so they don't have to scroll through every email with an
attachment..
2. Switch them to offline mode with automatic Send/Receives every five or
ten minutes. This will download the attachment and store it in the OST file
for them to access. Just be aware of the 2GB limit on OST file sizes.
