My mail queue is filling up with email for a domain that is gone. They were formerly my clients but due to non-payment of long-overdue bills and failure to respond to my calls and email, I shut them down.
I deleted all reference to their domains from my router, deleted their email accounts and removed their zones from my DNS. Unfortunately, a guy who does off-site (out of state, actually) secondary DNS for me has not yet deleted the zones for these domains from his name server. So, senders are still able to get a valid MX for their domains and mail still arrives for them. Since there are no appropriate accounts on my SIMS server for the arriving email, they sit in my queue. I had thought that SIMS would reject email to domains for which there are no router entries, with either a No-Such-Account or a We-Don't-Relay error. I've triple-checked my router and there's nothing that I can see which would allow such mail to be accepted. I have used the new address tester in the router of the latest versions of SIMS and an address like. [EMAIL PROTECTED] resolves to "name at SMTP(domain-that-is-gone.com)" which tells me there is no local delivery. In accepting such email, isn't SIMS open to a denial-of-service attack? Someone could just send lots of junk and fill the volume so that various processes failed. Curious. -- "Your new computer's not gonna be a Mac?
