Email server internet connection

I want to know if the way I have configured our internet connection is the best way.

We have two broadband connections with the same ISP and both connect to a Vigor 2820 dual wan router.

We have our own Mdaemon email server on site so on the router I have all port 80 traffic down wan1 and all email ports to use wan2

Users 35 of them still say the internet is slow (1MB up 10MB down on both lines).

I would try to monitor your network nodes to see if their are any log jams. You can get a free demo from Solarwinds -

Splitting your Wans the way you have sounds like a resonable approach. Anyone complain about email being slow?

You could run a speedtest here -

I would recommend using Thinkbroadband speed tests, and also Broadband Quality Monitor which will track the latency of both WANs for free.

 Broadband Quality
You be able to track the quality of both your broadband connections over 24 hours, you'll see if you are hitting a bottleneck, and maxing out your links, because the latency will get worse.

In my experience, users will always "complain and state slow" because they are comparing it with there dedicated 8MBps - 24MBps broadband links they have at home, which may or maynot have proxy/firewall or caches in the way.
The 2820 can load balance between the 2 lines. The users will notice slow browsing because they are constrained to 1 line. E-mail can be slowed down drastically without anyone noticing. I would open up port 80 to both lines. This will give the users a better response without significantly affecting e-mail delivery.
