Further comments on IP and domain blocking for *personal* mail servers: Just checked my maillog from yesterday.
70% of rejected mail connects came from hotmail, yahoo, earthlink and aol.
Umm, are you sure about that ?
You're right. Wherever it comes from, by blocking these domains I do not receive this mail. :-)
If you look at the message headers you'll find that nearly all of that (well for hotmail and yahoo anyway) is just spammers forging hotmail and yahoo addresses, the messages wont actually be passing through hotmail and yahoo servers...
True......I should have made that distinction. I simply block these domains.
Anyone in the world can send an email through any server in the world and make the From and reply addresses seem to be a hotmail address....
True... Either way - and from whatever source - I get rid of 70% of the spam directed at me by blocking these domains. (Based on the logs from yesterday - admittedly a small sample)
