Hi Dan, Diving in on this one without really understanding the background to the problem ... I don't run mail-servers, so this post may be useless, be warned in advance ... *is* useless, if you manage mail servers for third parties! ... All that said ... I used to have to deal with this issue of people sending spam, spoofed to have come from my professional address. Only ever send out digitally signed email, and put a notice on your website to that effect - that any non-digitally signed email can be ignored/reported as SPAM. Obviously you need to publish you public key, so persons can verify signatures. The above approach stopped virtually all people writing to me along the lines of 'why are you sending me SPAM'; a start, at least. Hopefully some did of course, forward on the SPAM to relevant agencies. :/ I did say this might not be solving the problem you have! But I thought as this spoofing is a big problem generally, others might be interested, especially if coming under serious 'attack' with this problem - as the volume of 'angry inbound' can be totally overwhelming/impossible to deal with in any sensible on-to-one reply, basis, when the SPAMMER is sending out 100,000's of emails an hour. The link I used was 'SPAM note' or some such; it did get clicked quite a bit, so I guessed, possibly wrongly, that it had some desired effect. The only real down-side to this approach is that you may not now become aware that the SPAMMER is out there, using your domain, etc, for their nefarious purposes. Though keeping an eye on the SPAM note hits, of course, gives one some generally idea when it's kicked off (again!)! <g> Best, LL -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --------------------------------------------------------------
