Right I am going to own up - I don't fully understand these spam filters and domain blacklists etc. I am getting a lot of scam letters from Nigeria these days. I always highlight them in Mailwasher and click Add to Blacklist. Is this what I should be doing, other than just delete? In fact, does adding them to the blacklist prevent others from that source? I see you can create filters, but that is a mystery to me. Help and advice appreciated.

I think the problem with many items of spam is that they change the 'from' each time so they still arrive. Having said that, I use Nortons and it must go partly by content as I get little spam these days.

Today I got a scam Nigerian email and I bothered to read it. It gave the name of a bank in Lagos. I typed in the name of that bank, intending to report the scammer who was using their name. This is what I found there:
Where to send your Nigerian scam mails.
There is an area on that site where they encourage you to copy paste the whole thing. I did that. I received a thankyou and we are dealing with it note.This MAY be useful.

I seem to remember that MailWasher can ignore entire countries can't it? If so, perhaps put Nigeria on the blacklist. Of course this does rely on the scam mails acually originating from Nigeria. Other than that, I think you'll probably need to resign yourself to just deleting the pesky things. They always seem to find a way through somehow.

Are you able to ditch your e-mail address and create another? That's what I did a while back and now I get virtually no junk. I currently have 3 addresses;

1. The newly created primary e-mail address (creating this one meant changing my entire account details with the ISP, I don't think that's possible with all ISPs). This address doesn't get used at all.

2. An online e-mail address (shopping - forums - etc). This can be easily changed if spammers/scammers latch onto it.

3. Friends (I actually have some ) and family. Again, easily changed if necessary.

Perhaps doing that would be an option for yourself.
