Hello, I'm not sure how to complain and where. But I hope that here we can start a discussion again. I'm quite upset. Is this the new world? A given mailhost (ran privately for smaller entities) can't send messages to T-Online anymore. 554 IP=168.119.159.241 - A problem occurred. …
Do you have an impressum page on your website? T-online will reject any mail from a server without an impressum. This happened to me this year and, after contacting them, they made it clear that I would not be able to send mails to them without that impressum.
Check this URL too: https://postmaster.t-online.de/index.en.html#t4.1
The sending IP belongs to a rented host (rented from a major German
hoster). The answer he (the owner of that host) got was about like this:
(translation by me):
Sorry, we only accept messages from proven
commercial or similiar servers. Please use the SMTP relay of your hoster
or your ISP.
I know that T-Online's postmaster announced this kind of behaviour, but
I didn't expect that they are going to implement it, as I saw enough
complaints here.
From my point of view they now force smaller MSP into contracts with
bigger mail relays, working towards a centralization of mail services,
which IMHO is exactly the opposite way mail was originally designed to
work as.
@mailops: What's your opinion?
Personally I consider this quite rude, and as a smaller ISP I'll be hit
sooner or later. As an Exim developer I'm asking myself why they
(T-Online) assume that I shouldn't run my own mail service.
