Due to the amount of crap now being received by email, I am considering using an email filtering service based in the UK.It costs £3-75p a month.
Is anyone using this sort of service. If so, have you had any problems and how effectively would you rate the system?
Cheers.

I don't use an outside service, but we use SpamAssassin and Procmail to filter. I just make sure to check the spam file each day for anything legitimate getting stuck.

See SpamAssassin.org - they also have some references to filtering (milter) options.

Best of luck,
Max

I think the general concensus is that they do work.

However, at the minute I am having some trouble. My work colleagues are getting messages saying that their email is not being passed on due to spam, however, in the last hour I have deleted a nigerian wanting to give me money, 2 people selling me viagra and a dial-a-prank email. I think I have it set on backwards somewhere :)

I use Matador on my PC at home. About 3 months ago I had such a chronic spam problem at home. The most I got in 1 day was 160! Thats not cool at all and this went on for a while. Tried a few programs but they sucked. My Dad of all people actually suggested Matador.

To this day I have not received another piece of spam. As for personal letters that might be filtered, well people can get hold of me other than on my PC........I hope;-)

Try ella at [openfieldsoftware.com...] . It learns what you like and what you don't like and doesn't just rely upon what is in the subject line.

What I want to know is when are ISP going to allow you to block generic things like block all domains and/or email addresses that contain numbers etc..? That would cut down on a lot of the crap.

At the rate the whole thing is going though the only way that it's going to be stopped is if it actually costs money to send each email.

>> I think I have it set on backwards somewhere

LOL. This is the exact reason I'm scared to try one. I've seen so much spam come in with such screwed up Subjects and Froms that it's obvious they're trying to beat the spam filters. And then I'm afraid that I might filter out legitimate email from clients who simply trigger the filter by accident.

Try MailWasher...

...and then look through some of the great threads [webmasterworld.com] we've had here about it...

Bill,
Thanks for that. I have checked the threads and they are very informative.
When you bounce mail, Does that really stop any more mail from that sender?
Mailwasher looks great, but what about online services where you can access your mail via a browser from anywhere and also see what spam mail has been stopped before it reaches your inbox. Do you think these would be more effective or do you not think it makes any difference?

I should have added..
Apart from the bounce facility, what advantage is there in deleting emails on Mailwasher as opposed to setting up filters in Outlook and deleting them from there? It seems to me that you still have to log on and look at them - and then delete them manually.
Or is there a facility whereby once you mark an email address for deletion, it is automatically deleted by Mailwasher and you don't even have to see it?
(Sorry to be a bit slow on the uptake)

Is there any software like MailWasher which can be directly installed on the server, rather than the local computer?

Thanks guys.
I have just downloaded Mailwasher and it looks good. Very easy to configure.
Am I right in thinking that you still have to delete manually as there isn't a facility for deleting and bouncing automatically?

I too am using MailWasher and find it pretty good.

You can designate senders as blacklist or friend and all blacklisted messages in the future will be automatically set up with delete and bounce as a default. When you have checked all messages sitting at your email service provider to be sure they are correctly identified, then you click on process and those to be deleted and bounced are processed. You are then left with the rest that can be passed through to your own email program, Outlook in my case.

I have a last remaining problem. The MailWasher filters only operate on text messages. I would like to filter out all HTML messages which would be initially classified as blacklisted. I would then scrutinize the list and mark those I wish to receive as Friends.

Does anyone have a good solution for filtering out HTML messages with offensive content.

That's debatable. I suggest using it sparingly. A lot of the stuff from Yahoo or Hotmail accounts is forged anyway so it won't do much good for those...sometimes it just feels good to bounce.

Apart from the bounce facility, what advantage is there in deleting emails on Mailwasher as opposed to setting up filters in Outlook and deleting them from there?
Once you've allowed Outlook to download the mail the damage is done in most cases. Mailwasher lets you delete and bounce from the server before it gets to your PC.

Am I right in thinking that you still have to delete manually as there isn't a facility for deleting and bouncing automatically?
You just process the messages through your filters. Those which don't pass can be deleted by Mailwasher.

The MailWasher filters only operate on text messages.
Not true. You can filter out HTML the same way you filter text. Check out these filters suggested by Mailwasher [w5hq.com].

Try obfuscating your email addresses on your web site. That should cut down on much of the nasty spam in the first place! :)

See a reply I just made to this thread:
[webmasterworld.com...]

My partner and I get approx 400 spams/day to our main addresses which have been around online business for the last 4 years. Method in above post is currently catching over 99% of spam, better than the 90-95% success I've had with techniques mentioned in this thread.

You can use POPfile along with MailWasher. I haven't but know people who do. They swear by it.

SpamCop in my opinion. Their server collects my emails (like webmaster@domain.com) from clients servers and everwhere I have an email address, washes it with the filter settings I have set and forwards what's left to me at my business email address. Average this month is 300 emails a day of which approx. 270 are spam. One or two false negatives a day and only one false positive ever. My current filter settings on SpamCop are:

SpamCop Blacklist bl.spamcop.net
SPEWS level 1 spews.relays.osirusoft.com
Osirusoft open relay inputs inputs.relays.osirusoft.com
ORDB open relays relays.ordb.org
Spamhaus Blacklist spamhaus.relays.osirusoft.com
South Korea korea.services.net
Osirusoft Open Proxies socks.relays.osirusoft.com
monkeys.com open proxies proxies.relays.monkeys.com
China cn.rbl.cluecentral.net
Nigeria nigeria.blackholes.us
Argentina argentina.blackholes.us
Brazil brazil.blackholes.us
And SpamAssassin Limit 8

It costs $30 a year and I would still use it if it cost ten times as much.
