Hi, List, my users are getting increasing amounts of "Mail Delivery Subsystem" mails, and I suspect spammers are using their addresses as senders. I have my servers registered with SPF, but now I wonder how could I stop this mails from getting to their accounts? I've tried to explain to them that spammers are beggining to use the spoofing techniques used in viruses, but they're just mad at it. Has anyone a sollution to this issue, or we must just get used to it?
BTW, I run SA through AMAVIS, on a Debian-based machine. Thanks in advance, Luis -- ------------------------------------------------- GNU-GPL: "May The Source Be With You... -------------------------------------------------
