comment Incoming mail from sender, MX record won't accept replies. How to block the incoming SMTP connection from that sender?
“If you don't mind dropping these mail sources, you can drop senders you can't reply to.” Yes, that's exactly what this question is asking. If you know how to do that, please write an answer!

Senders don't themselves have to accept mail, but they do need to have an MX record. If the sender's MX host refuses mail, I don't want to accept the incoming connection from the sender in the first place.

+1 for the update to the regex. I've incorporated that into the question for future reference.

No, SvenW's answer is not overall the right answer to the question. I've voted it up and made an appreciative comment though.

Thanks. I wasn't looking for making changes to the hardware (so can't evaluate whether they work in this case) but I appreciate the suggestions.

comment Please recommend a good mail server that compacts storage by use of hashing or other means?
An MTA is responsible for sending messages, which implies you're asking only about storage of messages queued to be sent out. Is that the case? If not, you might instead be talking about mailbox storage; please change the question if so.

Thanks. Currently, senders succeed in getting a message delivered, but then there's no way to reply back. By blocking the messages at SMTP time, with an explanatory message, the sender will at least know that the problem is at their mail transport provider's end. That will be an improvement over the current situation.

I can only refer you back to the part where I've said the reject message explicitly says the reason is “your host is an ADSL connection” (or various other phrasings). The PTR record for the host is correct. If they're rejecting based on a PTR record that is correct but they don't like, then that's what I'm trying to address in the question.

One of us is very confused. I answered your questions about rDNS. Do you think rDNS uses something other than PTR records?

Where have you got the impression that the DNS entries are incorrect? They're not; PTR and A records are present and correct. Also, the recipients have made plain that their reason for rejection is not poorly-configured DNS settings, but rather that ADSL is the criterion on which they're rejecting.

That is one of the black lists included in the aggregate checks suggested in JohnnyD's answer. The address is not currently listed at that service.

Thanks for the links, JohnnyD. The mail host's address gets a clear report from all of those services, so we can be confident it's not listed in a reputable blacklist.

The address is no doubt listed as “belongs to a range of addresses assigned to ADSL service”. While true, these lists appear to be misused as “nobody should ever be making SMTP connections from these addresses”, which is an abuse of the list; the address is permanently assigned to this service and is valid for use. So, the problem is the misconfiguration of the remote server blocking this address, not the list itself.

The explicit reason given, in a majority of these cases, is “your host is on an ADSL connection”. That's true, but seems to imply that the address is dynamic, which is false. To block merely because the client is assigned to an ADSL range is a misconfiguration.

Thanks, but this doesn't address what I've written. The mail server is existing for a while, and has adequate protection against unsolicited junk. I'm talking about adding a new restriction onto an existing mail server.

Worse, this will appear to work but will fail to show any accounts or groups that are not present in those files.

From the timing, I know that the difference in behaviour becomes evident too early for the operating system to be a factor. But I'd neglected that there is also a different boot loader; that bears further investigation. Thank you.
