but now there is none. Different path, but no reference to the alias. I had not noticed this issue, but it has been there for some time.
Probably since August 2020 when we switched over to our own mailservers.
Can't someline be added like before? An "Original-Recipient" header?
I have just checked some of my old mails and it goes way further back. I only see that 'Original-Recipient' header in delivery reports, never in normal mails. Also, they never say 'per@opensuse', also something else.
I also have a few aliases delivered to my account "firstname.lastname@example.org". To distinguish them, to direct them into separate local accounts, I use an extension -
per@address1 -> email@example.com per@address2 -> firstname.lastname@example.org per@address3 -> email@example.com etc
But you use your own server. I don't know if that would work with Telefonica.
The address extension is a standard feature, but you're right, it doesn't work with Telefonica, I've just tried it.
