Re: Mysterious delivery failure reason

Dave, ? ?MX lookup returned: lookup on : server misbehaving For a usual rejection case That text (and the three-digit code that should have preceded it) would have been issued by the member's email service during the connection from Groups.io. So most likely that service would have to be asked what it means. But in particular, port 53 in that IP address suggests that the receiving service mistook Groups.io as its DNS service provider, and attempted to look up that domain there. That's one seriously confused receiver. Also, I can't find any link between the user's domain name and the IP address Yes, Linode is a commercial service hosting Groups.io's web and mail servers. (I have sent substantially the same message to <[email protected]>. But maybe ? Good. Groups.io will want to make sure that its servers have the correct DNS entries in place. Or that there wasn't a glitch in the transaction with the receiver's service. But most likely this is not a Groups.io problem. It sounds like the recipient's server is rather confused about how to authenticate the message.
