If you havent set your MX for them, which I kind of assume you havent, I would take a punt and say the MX for your domain is stuffed up :-( Do you mean to use your email server at echidna.sbt dot net dot au ? If so, the MX values arent set for it, at least not from my side when I look using mxlookup.

Hi Voytek >I was trying to send to gnatsmartroad, and, it bounced. >what's that got to do with my MX..? A lot, as the error message from smartroad states that the email server your using doesnt have a valid MX. When I use telstra's pipeline, I cant get a valid MX for your email server either, but using connect dot com dot au's pipeline, I see you with no problems at all. I suspect this is were the "pluto.senet dot com dot au" is coming into it, smartroad thinks your email is being relayed through pluto.senet dot com dot au, so it is rejecting that email due to the spam rules. I'm not sure whats happening with the internet at present but I have also noticed in my Apache error logs, hits for files and directories that are not on os2site dot com, os2site dot net, and other domains I have here, its like someone elses domains have my IP address's. I have also had a big surge in CodeRed type hits being stopped at the firewall, including Nimda hits. I've not seen the error logs like this before, its almost like someone is hacking the root servers. Or Telstra's Windows network is breaking down ;-) Cheers Ian B Manners http://www.os2site dot com/ 4============================================== From: "Ian Manners" Date: Sat, 16 Feb 2002 04:28:56 +1100 (EDT) Subject: Re: [os2genau] CNAME etc Hi Ed > Can you explain to me what a CNAME is and what it does please ? First, here is a slice of my DNS file for ecs-site dot com. ; ; Definition of the mail exchanger for ecs-site dot com. MX 10 ecs-site dot com. MX 100 yarrina.connect dot com dot au. MX 120 warrane.connect dot com dot au. ; ; ;******************************** ;* Domain Address Information * ;******************************** ; ; Addresses for the canonical names ; ; Make entries for the generic parts of the ecs-site dot com domain here too www.ecs-site dot com. A 210.8.201.168 ftp.ecs-site dot com. A 210.8.201.168 mail.ecs-site dot com. CNAME mail.os2site dot com. A CNAME is simply an ALIAS for another Name or "item". A CNAME should however never be referenced by another alias/CNAME, ie, it should never appear on the right hand side of the database tables. In this case, as www.ecs-site dot com is hosted on the os2site dot com server, and I use Weasel as the mail server software, Weasel is not multi domain capable, so I can still have an MX (Mail eXchange) record for ecs-site dot com, and a reference of mail.ecs-site dot com by creating an alias pointing at os2site dot com's mail server, in this case mail.os2site dot com I could also simply make ecs-site dot com's MX record point to mail.os2site dot com. There are other reasons for having CNAME's in DNS records, ie, multi honed hosts. I'll see if I can dig up some web references which would probably give some better examples as well.
