Hi,

We are currently considering banning all external webmail services, i.e. Yahoo, Hotmail etc (we already have hotmail blacklisted).

Is there anywhere I can get a good list of addresses to go in the blacklist ??

I think you can get a list of known spammer IP's, if that helps. Search on google should do it.

Depending on your business, banning free a/c's might not be the best solution. So many people have hotmail, yahoo etc as their email a/c's you could be losing custom...

Nooo... I mean stopping our users from viewing their personal webmail.

www.aol.com
www.webmail.com (this is a bigger as with webmail you can check almost all internet based e-mail addresses)
http://webmail.nildram.net
www.ntlworld.com

I can't think of any more at the moment

www.mail2web.com is a popular one as it lets you access any pop or imap account so you don't have to sign up for anything.
twigger.### (loads of TLDs) does the same.

mail.com, mail.org, o2 and lineone.net are also pretty popular.
I'd visit BTOpenworld and try to log in to an account there to get the URL as many people will have those.

There are very many to cover them all, I'd do the big ones and then review the proxy or firewall logs every week or so looking for the odd ones that people try.

It won't be very popular obviously but webmail is a route in for unsafe mail so has to controlled...
Good luck!

there are thouands of these you need to block....good luck if you are doing it manually.

Nah, you can probably get away with the ones being used as long as you keep an eye on it.
Slightly more reactive than pro-active but people do get the message...

Just make it a part of AUP - block what you can, give the 1st transgressor a written warning & word soon gets around

Hopefully only need to go for the more well-known ones, I just wondered if there was any kind of importable list I could use.

Just had a look to see if I can export the list from surfcontrol, but I think they have managed to stop us from doing that as I can only export the ones that have actually been hit (since I last purged the database)
