AW: how to deal with t-online's blocking
Hi, only commercial websites and those of entities (e.V. etc.) require an imprint in germany. The "TOL problem" also occurs for private persons who do nothing wrong legally. And it also affects commercial services who do not host a website under the mail domain.

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. [...]

The mail log did say: Nov 30 12:17:08 mx3 postfix/smtp[220173]: EEF9C9F07F: host mx01.t-online.de[194.25.134.72] refused to talk to me: 554 IP=xx.xx.xx.xx - None/bad reputation. Ask your postmaster for help or to contact t...@rx.t-online.de for reset. (NOWL) I use the contact from the returned message.

Hi, I remember writing to TOL on behalf of a .net organisation. And request they whitelist the new IP of their server. That worked. The address should be in your logfile with the reject. Did you use that or some other channel to talk to them? So many companies ignore basic things like abuses. Or in this case invent their own whitelist. I bet nothing of all this gets them on a RFC-ignorant style list, where they belong IMO.

November 2022 03:09 An: postfix-users@postfix.org Betreff: how to deal with t-online's blocking Hello, My mailserver once had some issues on sending messages to different providers. I have contacted the provders and most of them were kind enough to resolve the blocking issue. Thanks for them (ATT, GMX, 1and1 etc). But t-online.de keep blocking me. I have contacted them twice and got the same answer: We only allow evidently commercial or similar operators to connect to our mailservers. So, as a private user please use an SMTP relay or e-mail gateway of your hoster or ISP, that you can use as part of your contract with them. Their support will surely help you to configure your system accordingly. That's so strange policy to permit only commercial company to send messages to them. But there are many small companies/org who have their own mailservers, which can't send messages to t-online directly. How do you think of this behavior? Thanks.

Hello Henry, I am running my own email-server as well and can connect to t-online. I assume Viktor is right that they somehow check the imprint of a parallel web site. My website does not indicate I am offering email service commercially, which in fact I do only to organizations I know personally. I did get blocked by Outlook though and changed ip address to resolve that. Your data center might be suspect to them. You may want to try a VPN to a different one that has better reputation. Btw - what "encryption" are you doing? Regards, Joachim -Ursprüngliche Nachricht- Von: owner-postfix-us...@postfix.org Im Auftrag von Viktor Dukhovni Gesendet: Mittwoch, 30.

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.
