Yep, I've definitely noticed it :) It got me annoyed enough to turn Postfix into a mail rejecter :) Here's what I've stuck in /etc/postfix/main.cf: [snip] Note that you need permit_mynetworks under the helo restrictions so that you still accept email from Outlook Express clients and the like (if this is your SMTP gateway for ISP customers) - OE will not present a FQDN for itself regardless of operating system (I believe it presents the NBT name).
I think you'll find just about all end user email software does this.
I'd be curious to know what sorts of policies ISPs have within NZ, and why. Before I put in my filters, most of my mail was spam - and this just isn't right :) Apart from the UCE recieved recently (I too got the "DHS Clubshop" mail) from within NZ, our local networks are really quiet.
I've been trialing orbz and ordb in the last couple of months (not related to orbs) and they've been very good. Naturally I've kept a very close eye on it, but I've only had 2 instance where genuine mail wasn't getting through that I know of - and in both cases they WERE actually open relays. I was easily able to add an exclusion for those two servers until they got off their ass and fixed their open relay. (Both did after a couple of weeks) Both also have good and fast removal policies so they're not the sort of list that once you get on you can never get off...(ala the original orbs :) When I first started using them it cut the spam by 80%, I'd hate to think what it would be now without it.
Certainly, I've been tempted to just block addresses from Asia... Most of the spam I saw before I put in my filters was for cheap Thai sex prostitues and whatnot. I'm just not that kind of girl :)
Well 90% of the ip addresses that I found were all Korea :/ One extremely prolific spammer in case anyone is interested is 4.42.113.104, which belongs to genuity's netblock. Even after blocking them with 550 Rejects, they're constantly hammering on our server every half hour. I suspect there is fat chance about Genuity doing anything about them, I've heard they don't have a good rep when it comes to shutting down spammers...:) Regards, Simon - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
