Thanks for the suggestion, I'll check that out. But I'll try it on other mail servers first. While spam on the LUV server is a problem for the president it isn't a problem for regular members who would have a problem if I broke email...

There are lots of significant mail receivers such as Yahoo and Verizon that rapidly block IP addresses due to accusations of spamming. While it's annoying that some big senders use lots of addresses it does mitigate those problems.

I don't know whether the benefit would be worth it for the LUV server. I might get Andrew Pam to help with anti-spam measures. I think he gets more spam through the LUV server than anyone else. ;) -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list [email protected] https://lists.luv.asn.au/cgi-bin/mailman/listinfo/luv-main
