Re: [9front] 9front mailing list blocks my messages without notice

[sirjofri+ml-9front@sirjofri.de]

Hello,

so let's try sending another mail and see if that arrives. This time from the mail address that's subscribed to the list.

That's not nice, but even then, that's how it is.

Does the mailing list block messages from addresses that are not subscribed?

Is it possible that it's something about the helo/ehlo string? Because email.fairemail.eu is the mobile client I use and it's its ehlo string. I currently changed it to sirjofri.de, it seems like my mail server does not overwrite it when relaying mail to other servers?

On the other hand I never configured mail server relays myself, so I don't know exactly if mail clients send mails to the destination or the own mail server (relay) first.

If it really is the ehlo string this mail should arrive.

I don't think I wrote mails from this address other than the subscription mail itself. I prefer using the +ml-9front address for automatic sorting of mails, but still send from the "untagged" address.

If 9front mail server is unable to handle these plus signs I can change my subscribed address.

These are from my old mail server (uberspace). I think we can ignore them, (if they didn't add my domain to some blocklist).

Really, don't ask me why spf failed here. I didn't change these and they are configured to check the mx records (which points to the new server oat.nine.sirjofri.de). Since they are only one day I think these will not happen anymore.

So let's see if this mail arrives or look how we can fix these issues. Thank you for your response.
