search of previously known spammers of emails?
Discussion
I get the standard emails coming through to the business email that are misspelt english and bad grammar, these just get deleted.
Im now getting alleged faxes being sent to my email that contain zip files (have not and will not open them).
One I can trace to a Durham which seems to be a building company, they will be contacted to ask if they have sent me anything.
The other I cant track, so was wondering if there is a central resource of all the spamming emails that have been used recently?
Im assuming they are both spam, but want to make sure... they look like this:
Fax Message [Caller-ID: +44 (0) XXX XXX XXXX]
Date: 2014-04-25 16:52:56 UTC.
Pages: 13
Reference number: FF4133D276732B5727D7

The junk e-mails come from infected or compromised e-mail systems and workstations. In 99 percent of the cases there is absolutely no point in trying to trace. Your best bet might be to employ an anti spam system that uses dns blacklists that will stop your e-mail accepting e-mails from known spamming ip addresses. Search for spamhaus and spamcop, two very good free dns blacklists. You can also report the spam to the isp, which you can work out by doing who is lookup on the originating ip address.
if you get a lot of spam and viruses then i would recommend using an online spam filtering system such as gfi mail essentials, to filter the spam and virae before they get to your e-mail system or workstation.

The problem with that is - as you say yourself - they often originate from compromised PCs of innocent folks. If you block their IPs by using spamhaus or other variants then you're potentially losing out on custom.
I find a better spam limitation system is to put contact links/email details as an image where they can't be scanned by spambots and also don't use the standard email addresses such as info@, admin@, support@ etc.

Innocent folks' computers don't originate emails, they use mail servers to send email. Their PC should often not connect directly to a recipients mail system. And as infected home PC's are most likely to send SPAM then they should be blocked as soon as they get infected.
DNS blacklists work very well for free so long as you stick to reputable blacklists.
Displaying your email addresses in an image is one tiny measure with minuscule impact and is not 'better' than any other measures.
When people email you, your email address is kept in their recently used list, or their contacts, and/or their sent items. Your address is harvested by Trojans that scrape this data from your correspondent's computers. If you use your email address on websites, even if only to register an account, then from time to time they will be hacked and your email address harvested. Some websites will sell your email address.
Defence against spam requires several layered measures, the most effective of which I have described.

It's not going to be the company in Durham, as mentioned earlier
The thing with email is, it's so easy to spoof who the sender is, you'll never track the originator so it's a constant battle.
There's a few things you can do to stop it, anti spam products and checking against IP addresses of known spammers in an ever updated database
The company I work for has just launched a free service called Inumbo which is partnered with Rackspace, assuming you're not going to run a Gmail or web mail account through it, and it's under 10 users, it's free. You'll find it through Google
There's other options, spamcop, spamassassin and various things you can install, I think ClamAV has an anti malware option as well if you want to try a few out.
