This may or may not apply to you, but if it does, there’s a quick way to filter out a bucketload of spam.
Spam can be sent to an address that looks like this:
email@example.com or firstname.lastname@example.org
instead of email@example.com (ie firstname.lastname@example.org)
That is something in the form of “email@example.comISP.net”
What’s happened here is that the website has been placed in front of the proxy at my ISP.
Yours may look like firstname.lastname@example.org.
Well: no one I want contacting me uses that kind of address. Ipso – if the address contains “@proxy.myisp.net” I have set up a black list to just dump those emails. I never see them. If you can’t set up such a list via your webmail, then you can use it as a regular filter/rule in your email client.
