OVH
by Klaus Ethgen 27 Apr '21

27 Apr '21

Hi folks, do any of you know just one legit service that is hosted by OVH? They own massive amount of /16 networks and many of them are already in my blocklist as I have seen massive server attacks from that OVH networks.

Does anyone have any idea what sort of rate limits are used by Office365 ? We seem to be hitting $SUBJ more and more often, so we have been scaling back delivery frequencies. It just seems a bit random and arbitrary. -- Per Jessen, Zürich (19.4°C)

New glue record, transfer of domains and such things
by Mueller Urs SBB CFF FFS 15 Apr '21

15 Apr '21

Hi there A friend reminded me to use the list, as it is sometimes a bit quiet here. ;-) My understanding of a glue record is, that the registrar of a domain is responsible to configure them (in my case at home, this was Cyon, but they were a bit puzzled, as they don't do this very often). Just to understand this technically (I'm perhaps totally wrong): - Domain registrar receives customer order (put dns.xyz.zyx with 1.2.3.4 as glue record into some system) - Registrar has an interface (fax, carrier pigeon or something similar) to tld registry, which can save the record to its database If I further change my registrar, this doesn't affect that entry, but any change has to be ordered through the new registrar. There is usually no way to do this myself (if the registrar is not offering such an interface). Please help or correct me. Thank you.

FYI: COMLOT Geldspielgesetz Key expired
by Jeroen Massar 14 Apr '21

14 Apr '21

As it is 1 april tomorrow, some things expired yesterday: Not After : Mar 30 13:28:58 2021 GMT That thing is.... the COMLOT key to verify those Geldspielgesetz keys for their fun list of worldwide casinos: https://blacklist.comlot.ch/comlot_blacklist.txt see full cert details below. You can get the key with or attached: $ wget -vS https://blacklist.comlot.ch/blacklist.comlot.ch.pub --2021-03-31 16:50:00-- https://blacklist.comlot.ch/blacklist.comlot.ch.pub Resolving blacklist.comlot.ch (blacklist.comlot.ch)... 194.187.88.5 Connecting to blacklist.comlot.ch (blacklist.comlot.ch)|194.187.88.5|:443... connected.

Mail rejection at bluewin
by Peter Rohrer 07 Apr '21

07 Apr '21

Hello everybody Since yesterday, we see a lot of bounced messages to bluewin addresses with SMTP code 554, for example: relay=mxbw-bluewin-ch.hdb-cs04.ellb.ch[195.186.227.50]:25, delay=0.16, delays=0/0.01/0.09/0.05, dsn=5.2.0, status=bounced (host mxbw-bluewin-ch.hdb-cs04.ellb.ch[195.186.227.50] said: 554 5.2.0 sc976: Rejected due to policy reasons - https://support.bluewin.ch/provider/bounce/XXXXXXXXXXXXXXXXX[redacted]== (in reply to end of DATA command)) Unfortunately, sc976 is not documented on https://postmaster.bluewin.ch/content/de/technical-details/ We can't see any general pattern behind those rejections (hosts trough our entire IP range are affected), switching to a different IP address for delivery works in most cases. Do you see the same and have any insight what is going on here? Greetings Peter

Hello Simon, Oops of course yes we found "NO" evidence... I should have re-read myself before sending the post. Thanks for pointing that out 😊 and for the cheers. Kind regards, Sébastien -----Message d'origine----- De : Simon Leinen <simon.leinen(a)switch.ch> Envoyé : mercredi, 7 avril 2021 10:30 À : Sébastien Riccio <sr(a)swisscenter.com> Objet : Re: [swinog] Mail rejection at bluewin Sébastien Riccio writes: [...] > It's the 3rd time it happens in two weeks and we found evidence of > unusual SPAM activity from our servers that would justify such a > ratelimiting/rejecting. You found evidence? Or is there a "no" missing somewhere? (Just trying to understand.) Cheers and good luck with the delivery issues! -- Simon.

G.Fast DSL modems - bridge only
by Jeroen Massar 01 Apr '21

01 Apr '21

Hi Folks, So there is the list: https://www.swisscom.ch/dam/swisscom/en/ws/documents/E_BBCS-Documents/e_bbc… Anybody got a recommendation out of that for a bridge-only G.Fast modem? Apparently FRITZ!Box 7582 does not do Bridge mode, but Zyxel XMG3927 does. Cisco C1113-8P ISR is a bit much for my purposes (and at 800+ bit much too) Anybody has any positive/negative experiences and/or other recommendations? Greets, Jeroen

DNS is ambiguous and reverses do not always match forwards. Including the actual IPs can thus be very useful... That is, if you actually want it resolved. You might want contact swisscom directly (good luck with that) or at least your ISPs that provide the connectivity, they might have better chance at contacting them. (taking transit over swissix is a fun one; but yea it is not that swisscom likes to peer, what else would a monopoly do) Greets, Jeroen
