Yup, so now I'm trying to setup things so that my postfix routes all emails to @charter.net users via my charter login, but all others default to normal MX lookups and email sending. I've got my saslpass, transport_maps and other stuff setup, but it's not quite working. More reading and re-reading of the docs and this list's archives, since I know this has come up before. John

Re: how to deal with t-online's blocking
The issue has been resolved by getting reply from t-online: "We will unblock your IP. Please notice that it may take up to 24 hours until the change shows acute effect. Please excuse any inconveniences, but we do not see other possibilities to react to the millions of junkmails we receive at present. Thank you for your appreciation." Thank you buddies.

I'm in the same boat with one provider, charter.net, to shame them publicly. They block my mail host (with proper SPF records, reverse DNS) mail.stoffel.org for some reason.

Re: how to deal with t-online's blocking
> Those are obligations for web sites. But what about a mail sending domain > without web site ? As far as I'm aware there is no obligation (by law) to provide a website with legal info for e-mail only domains. Companies in Germany are required to include that information inside *every* email anyway (usually in footer). T-online wants to know your mailserver's ip addresses, checks matching forward/reverse dns and (usually) a website within your mailserver's domain with legal info - this is all about your mailserver. You do not have to provide this info for customer domains relayed through your mailserver. Best regards Gerald

Maybe it can be applied to everyone having a mail server (which is able to receive mail) as well. In Poland, where I live, our Electronic Services Act ("Ustawa o świadczeniu usług drogą elektroniczną"), which regulates this, clearly says that only an entity which provides services electronically to customers as a part of business activity (these services can be free for customers, but must be a part of a business that generates revenue in other way - eg. via ads) may be considered a "service provider" with regard to this regulation. This seems much more reasonable for me than the German approach. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."

Those are obligations for web sites. But what about a mail sending domain without web site ?

While it is actually a legal requirement *in Germany* (not in whole Europe!) and for *German* websites to have such an imprint in general, in this case it seems to have actually nothing to do with legislation - there is no such legal requirement for mail senders, and they seem just to pick up an existing legal construction and put it into their own requirements for mail senders. So you either comply to their requirement or the don't accept mail from you. > Also what exact check > are they running? Do they verify the addresses and phone numbers at > all? As I can understand from the discussion on "mailop" list, they don't seem to be actually verifying anything. They only check if the imprint is present and the data looks plausible, ie. isn't obviously fake :) > I am pretty sure most Australian companies would fail to meet this > criteria (for example I just look at the Telstra - > https://www.telstra.com.au - website and I can't see where Australias > largest telecommunications operator fails this test, and I'd hate to > think of the number of Telstra customers that would fail to send email > to these mail servers (most of who would get belligerent at bounced > email). I guess they are just accepting large and "well-known" senders. But for small senders, you have to go to the process described. > I know that I don't want to, and am not required to, provide > that information for any of my domains, or domains that I host for other > entities. Me neither :). Someone recently reported on the "mailop" list that he managed to unblock several servers without the need to provide the imprint - so it looks they don't always enforce this requirement, but usually they do. If you want to discuss more about this topic, I suggest you join the discussion on "mailop" list, as it is quite active there: https://www.mailop.org/ (btw. this site has an imprint - called "impressum" in German - and it lists a New Zealand address) -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."

My question is: How do they deal with non-european entities who do not have such legal impediments in their jurisdiction? Also what exact check are they running? Do they verify the addresses and phone numbers at all?I am pretty sure most Australian companies would fail to meet this criteria (for example I just look at the Telstra - https://www.telstra.com.au - website and I can't see where Australias largest telecommunications operator fails this test, and I'd hate to think of the number of Telstra customers that would fail to send email to these mail servers (most of who would get belligerent at bounced email). I know that I don't want to, and am not required to, provide that information for any of my domains, or domains that I host for other entities. This just highlights the problems with internet, and general IT, related legislation/regulation. Another example of a problematic issue is a requirement by the Australian government for anyone working on products that use encryption to insert a backdoor that law enforcement can activate if requested - a requirement that after legislated saw many Australian companies offshore work. - -- Nikolai Lusan -BEGIN PGP SIGNATURE- iQIzBAEBCgAdFiEEVfd4GW6z4nsBxdLo4ZaDRV2VL6QFAmOHXaEACgkQ4ZaDRV2V L6Q3Qg/+OzWVAVBCZrS0SmvLm0cYQHvVnFf35ucIs8PzZ+vGtoc59iZjw+dbo8/p ZpEV4sY/jdI4d//owTTJgpNLpEwcnrmk6X6yAno2TBqqB0OURJJ/ueIRpPtkuUlW YB0Dv3qJwS5oRW1t0572W5xSDz6A+AYA1WYhD/TTMftQnBzlPOcDTqVjWKxxy6bg jCgLyLuZFSXZlxW5g2TNVnqVk3P3E9h1FPqNYRP75oIPKbcqIZG4wxmqFBJuMs+n pR6g3tpx+BMzGHbPxS/PVZiC8+hFjnE32Lw5U/MidU4fsUPai6KkcEJaWO+6g6sn Mdm+k+yhczqYkd3lBYZBtSB7+6Q7r0pTKtpudjvfmsTmHedossxSCkjc0XT/kaaE +SKF4yMYMAlC1QB4l3IBfdrD37EaZ5UpAAAIGEP++S9fqBB4rMLLnOQDOQnOSGk3 KLPYTZ8ebQ+M3XiMDEpKEUQuDMvimOrJ1DB0flM13l6senXUV1pHZadovo6t+gfv 0zBcaf3JWIO1/wFae5voB9jnRfWytxZYA03lGShj2ZYOYxOMpgGeNDWLPEbbhJdR fuTXrXs9Bqg6MnayPE9E9YvZZPOaCRXleXOtFYXvSM6f0BDyEAeA0tDacbIZHDW/ 4xeSHHCqyHv76J7V0vnEkgNocsd1sjmIpcgbT2Hapz/GBZlqabI= =hL0i -END PGP SIGNATURE-

Most likely this is not their actual policy, but rather a way for some underpaid level-1 tech support staffer to close your issue. See https://postmaster.t-online.de/#t4 for what appear to be the actual requirements. They do appear to expect sending domains to have a website, public contact addresses, ... but a requirement to be a commercial operator isn't there, best I can tell. You could try to escalate after politely pointing to the above page and pointing out that it does not in fact prohibit suitably operated personal mail servers. -- Viktor.
