Well, you've been doing this longer than me, but that's not my interpretation of the situation... :-) The job of standards like RFCs is to *define the interface between syntax and semantics*, as I see it: they tell you what the data *means*. That's information that's in the domain of end applications as well, as I see it: the MUA should care what the RFC thinks about the semantics of that data, since everyone else is already singing off that page of the hymnal. No standard forces a telephone to use NPAs rather than ZIP codes at the front of a phone number, I don't think, but you won't interface with the network (for which Bellcore's "Notes (heh) on the Networks" is that standard)...

[mailop] Is Spectrum trying to sunset rr.com and twc.com emails?
A client got an email that appeared to be from Keap, or maybe InfusionSoft, suggesting that Spectrum was trying to do that, and that users shouldn't add contacts with those emails unless they were "bone-fide" (which was my only hint)... but my experience of email carrier buyouts is that no-one *ever* sunsets the domain names, cause there's no real reason to do so, and it pisses off end-users. The email also pointed to this domain name, which looks semi-official, and I can't decide if the whole thing is some clever spear-fishing attempt, or just someone who misunderstood something and is trying to be helpful. Does anyone on the list know if there's such a sunset policy in process? Cheers, -- jra -- Jay R.

[mailop] Spectrum webmail folks around?
My sister's inherited tampabay.rr.com account -- the only one we have to look at your webmail client with -- is unreasonably slow in retrieving mail from folders. On my 16GB i7 with Win 10, it can take on the order of a minute to open a folder with 3 messages in it; much longer for things like the Inbox. Ridiculously longer on less powerful devices, like her Android tablet. I'm told this is a pervasive problem with the webmail service.

Is there someone on here from outlook.com or the protection subdomain, who can a) tell me how I *would* clean that up -- the linked page of error codes mentions Spamhaus, but they seem ok with me too, and b) clean up either the SMTP error message you're sending out or the table you tell people to look it up in? :-) Cheers, -- jr a - Forwarded Message - > From: "Mail Delivery System" > To: "jra" > Sent: Wednesday, May 27, 2020 7:13:30 PM > Subject: Undelivered Mail Returned to Sender > This is the mail system at host franklin.baylink.com. > > I'm sorry to have to inform you that your message could not > be delivered to one or more recipients.

Sure. At it's most fundamental level, giving web browsers a different way to do DNS lookups overcomplicates debugging of problems by at least a couple orders of magnitude, even before you multiply it by "trying to get a straight answer out of the end user". Everything on a machine should use the same OS provided facility for looking up DNS. Additionally, nearly as I can tell, the aptly named D'oH is solving a problem that *users* don't have.

It's possible you might have misunderstood my concern. If I'm an IT type, and I'm trying to diagnose why *you* can't get to a website, all my other tools -- which were built atop the system DNS resolver -- are likely going to give me false negatives... as the telco guys used to say, "the trouble's leaving here fine!" I can't *tell* why your problem is happening, because I don't have diagnostic tools built atop D'oH *and* configured for what invisible server your browser is using to do lookups -- which might be different from browser to browser. In short, this multiplies the complexity of diagnosing an everyday problem... and the complexity of my monitoring system actually *monitoring* anything... by between .5 and 2 orders of magnitude. That's an added workload for which my permission was neither sought nor granted, nor has my budget or staffing been increased. It is merely the latest (the adoption of systemd by substantially *all* the Linux distros being one of the earliest) example of small decisions with Big Impacts being taken in a fashion which seems to me not-at-ALL engineering driven... which is the way both Linux and the Internet *used* to run... which is how they got here.

[mailop] Charter/Spectrum Tampa SMTP relay question
A couple days ago, a client started getting 550 errors on their outbound mail from a local install of KerioConnect, saying that the From had to match the email address in the SMTP Auth -- which of course it wouldn't, domain relaying doesn't work like that. This sounds like a deliverability policy change, and I hope it's obvious why I don't even *expect* the tech support line to know what I'm talking about. :-) Can anyone in Spectrum confirm or deny, and maybe tell me what the expected way to do this has become now?

Well, I have it from a Charter person that they no longer permit relaying for ANY accounts, business or residential -- not through their mailservers, anyway. Haven't for a long time, is the impression I was given; we were just lucky that the implementation took this long to get to our mailserver in/for Tampa. So it's flip off relaying and see if the cableswamp is still getting blocked everywhere, or find a relay service on a "real" IP in a datacenter somewhere. Cheers, -- jra -- Jay R.

I don't have 5322 swapped in just now, but doesn't rewriting that header violate it?

Well, you've changed the field here; if you're only talking about a *terminating* MTA, not a transit one -- accepting incoming traffic for your own mailboxes -- then how tightly you need to adhere to the RFCs is probably "not as much". But it would only be the MUA; the originating MTA shouldn't be rewriting headers it's not supposed to either. Cheers, -- jra -- Jay R.
