How can I tell which computers are sending SMTP email out of my network?

I manage a network of 10 PC's. We have been recently blocked from sending emails to a few domains. Afer performing a full and thorough virus scan on my computers and server, we still seem to be blocked. Is there a tool (free preferably) that i can set up to only allow SMTP traffic to originate from my email server?

your network will have a router or a firewall ( or both ) that will allow you to set up access list - you need to set up a filter that only allows your email server to send smtp traffic - ( all other devices will get their email from this server ) - also worth making sure that your server isnt configured as an smtp open relay .. as it could be used by spamers to relay messages and may be the reason your are being blacklisted ( you need to ensure that youre mail server only forwards email from addresses on your network - or that have been authenticated ) search for open relays or spaming

From what you have said I do not think that a virus is your problem. You say that you manage a network of 10 pcs? Did you inform your ISP of this as it could be against your contract?

This may be the reason that port 25 has been blocked.

If you want to run servers, then you may need to upgrade to business account, where there are no such blocks.

Sorry for not being able to offer a quick fix!

In the meantime you can download a Network Traffic Monitor from http://www.tucows.com/preview/418063. It is shareware so it is free.

Edit: Am I getting thumbs up for ironically saying "God will deliver" or for calling Another Jerk a "bastard"?

Step 1) Break into a Best Buy.

Step 2) Break into a Family Christian Stores.
I would write to Bill Gates...also go to 2nd hand stores and just ask! good luck
what kind of church you are running that needs100 - 200 computers? :O

Pray to God. He can, after all, fulfill anyone's wish, right?
mmm I am no expert but.

If you where in the USA I would have told you to get to be a registered non profit organization and try to find a company that is throwing away their old equipment to make room for newer one. The purpose of being a registered non profit is that the company can claim tax benefits from the donation. You could have the same to donations.

Since you are in Africa, things are more difficult. Much fraud comes from that country and people are hesitant to help. If your church affiliated with any mayor movement, ask them for help.
Steal! :-D

One piece of technology (not computers) that you think will have a major impact on the Criminal Just

Using the Internet, books, or journals, find one piece of technology (not computers) that you think will have a major impact on the Criminal Justice System in the near future. Explain why you think that technology will have such an impact.

dna, because there is very little doubt!

I also agree on the dna system. This procedure is fairly new (if u compare it to the years the criminal system has been in existance) and yet it has been able to solve many crimes around the world. Even cold or even closed cases that at the time seemed to have no solution.
Without a doubt, it will be the GPS Systems.

With a procedure no worse than a flu shot, we will be able to inject a chip into the hardest of criminals so when we let them out, we can track and know where they are at all times.
At some point in the future, scientists will be able to develop effective tools to determine the validity of a person's statements based on electrical and chemical reactions which occur in the brain when a person responds to a direct question.

These tools will need to pass rigid validity tests and be acceptable as evidence in criminal cases.

If and when people understand that their lies can be detected with the same certainty as a DNA test, many will tend to mollify their behavior beforehand.

When you open up the case it is usually the big brick at the top of the case.

It might look like this:

Can I boot windows Vista into two different computers?virus protection software

You can use the DVD as many times as you like, but your product key will only work on one system..

It will install and work fine on the second system, but after 30 days you would be completely locked out..

i dont think there is any software like that. what u need is the hardware, not the software

You don't need a software program, you need some new hardware. You need a KVM switch.

Never heard that before.
your looking for a KVM switch, they are pretty cheap i prefer linksys kvm's as they have very simple switching... on a side note: ensure the kvm supports keyboard reset on switch... as ps2 is NOT hotswappable either must be usb or have that reset ability
Not through software. Use something called KVM like the one from IOGEAR.com
