OK, here's the story... Oh, Arthur, your SPF rejected me due to what is likely a YATS (Yet Another Telstra Screwup); I've since removed the record (it was just a place-holder anyway) but I forgot to update the TTL first. First, for the non-Aussies here, a simple glossary: NBN: National Broadband Network. Also known as No Brain Network, it's our national network infrastructure, powered (if that's the right word) by an ugly mix of technologies, viz: FTTP (which I have), FTTN (which most people have - sort of ADSL on steroids), FTTC (a new innovation), HFC (for those with cable), and for all I know tribal drums. Supposed to be FTTP to everyone, until the incoming conservative government decided that FTTP everywhere was far too good for the sheeple. Telstra: Technically Telstra BigPond, it's the biggest ISP in the country, one of the most expensive, and likely the worst, service-wise. Fondly known as T$, Helstra etc, I think the only reason I stick with them is Stockholm Syndrome (that, and a 2 year contract). Now, you cannot contact NBN directly; you have to go through your ISP (in my case T$) i.e. speak to the monkey, not the organ-grinder. OK... Full story for the morbidly interested available on request as a redacted version of my complaint to Telstra; hell, if I'm in an ugly enough mood I'll put it on my web page (it's an RTF file). My NBN service was cut off on 25th March, when NBN themselves not only sliced through my fibre cable at the adjacent pit but for good measure also disconnected it from the concentrator in the next pit; they are yet to explain just why, but they couldn't've done a better job of sabotaging my service if they'd tried. After much to-ing and fro-ing with T$'s helldesk (broken promises to turn up, return calls, etc), I finally had service restored on 20th May; that's 57 days (yes, I received a credit for lack of service, but not for the mobile (ObUS: cellular) calls that I had to make on a competing service). A nice new wireless router was supplied with automatic (I think) 4G backup (naturally with little documentation), but I realised that the port forwarding rules were the same as my old router (a Technicolor F@st 5355). Of course I got auto-unsubscribed from various mailing lists; the trick was to figure out which ones... FreeBSD-ports didn't notice my absence, and neither did Krebs on Security; I've since tracked down a few more and re-subscribed. Now, this is where TUHS comes in. Hmmm... Awfully quiet, yet it's supposed to be an active list. Am I still subscribed? Quickest way to find out is to post to it, and a well-run mailing list will return a snotty-gram along with an URL. Did I get one? Nope. Was it accepted? Apparently so... So, why isn't any traffic coming my way? And for the smart-arses (ObUS: smart-asses) out there who think I must be blocking it, nope, I watch my mail reject log like a hawk (I have all sorts of reporting scripts) and Minnie was definitely not there. Are you still here, Warren? I did email you, but no reply so far (and no reject either, otherwise I would've spotted *that* too). If anyone has a better way to determine list membership other than by posting to it then I'm all ears/eyes; there are just too many ways to subscribe these days (not everyone uses Mailman, and some are by invitation only). Happy, now? Hours spend on this sh1t so far, and hours yet to go... -- Dave ^ permalink raw reply [flat|nested] 6+ messages in thread

I'm posting this here so that Dave can read it in the web archive. I'm guessing the problem is the one Dave identified earlier: > You need to grok Sendmail's log format (and SMTP in general), but it means > that Minnie connected to my server, waited the requisite time for the greeting > banner, and then shat herself when she saw my ginormous banner and dropped the > connection without so much as a good-bye... i.e.a multiline response to the HELO/EHLO which meets the RFC specs. > That simple measure, along with the greeting pause and some simple RFC DNS > checks, block a lot of the crap. I've just subscribed to the Postfix mailing list, and I'll ask on there if there is a configuration change I can make to allow my Postfix client to deal properly with Dave's multiline HELO/EHLO response. And why it can't at present. But if someone here already knows, could they let me know?! Thanks! Warren ^ permalink raw reply [flat|nested] 6+ messages in thread

The greet pause seems longer than I'd choose, but I think it's less than 60 seconds. Any reasonable mail server should handle that. So that shouldn't be an issue. > I've just subscribed to the Postfix mailing list, and I'll ask on there > if there is a configuration change I can make to allow my Postfix client > to deal properly with Dave's multiline HELO/EHLO response. And why it can't > at present. I'd be surprised if Minnie had a problem with the multi-line greeting. I think Postfix (if that's what Minnie is running) has been dealing with multi-line greetings for a while. There's also the fact that—I suspect—Minnie has been successfully delivering THUS to Dave's server for a while. So unless Dave's multi-line greeting is new.... > But if someone here already knows, could they let me know?! Do you have errors in your log?

Well, it turned out that I *was* blocking Minnie, but her name was not in the logs; it was just an IP address that ended up on my woodpecker list... I just saw my first message from TUHS :-) Sorry for the noise. -- Dave ^ permalink raw reply [flat|nested] 6+ messages in thread
