Question about EFM

[steve3]

I found a list of over 33,000 spam email addresses. I have been trying without sucess to add these to the Black list by copying and pasting them to the box. When I paste them my browser will lock up for several minutes and finally they appear and then when I hit the Update filters button, the browser gives me a page not found error. Is there a problem adding this many address or is there an easier way of doing this. Thanks.

Steve,

Please do not create whitelists or blacklists that contain upwards of a thousand addresses. This is a problem. It uses too much server resources to test such a large list of addresses and requires too much processing time per email.

Blacklists and whitelists should be rather short.

Moreover, there is a very small chance that you will receive spam from very many of those addresses.

I would suggest, after setting up EFM, that when you notice spam getting past the filter that seems to come from an email address that is re-used frequently, then go ahead and put that email address in the Blacklist From filter. You should only use the Blacklist from filter for email addresses that continue to send you email that you do not want, on a recurring basis that you have personally observed.

True... Most of them will be bogus.

Well, yes, they are bogus. But that isn't quite what I was getting at.

My point (not clearly made) is that it is so easy for the spammer to just make up new email addresses to put in the From field, that the ones on that list will not be an effective filter for very long, if at all. The spammers are constantly making up new addresses to put in the From field.

They are usually all bogus addresses, to boot, as you mention.
