Thank you very much!
After changing receive_list_copy from false to True, I again get my own message.

Thanks a lot, Stephen! You wrote:
I don't understand why it is "lrs@dalen.lamasti.net" and not "lars@lamsti.net".
My account name is lrs, but I have an alias of lars.
Local aliases don't matter DMARC, but the domain vs. subdomain could. I think that because of the "sp=quarantine" in your DMARC record, that should not matter to DMARC policy, but I think it DOES matter to DKIM validation, as described here:
Possibly you have a rewrite rule in the MTA. My guess about nondelivery is that dalen.lamasti.net is covered by the quarantine policy:
_dmarc.lamasti.net descriptive text "v=DMARC1; p=quarantine; " "sp=quarantine; rua=mailto:dmarc@lamasti.net; fo=1; ri=604800"but it is not covered by your DKIM signature. The signature probably has "d=lamasti.net", but this value must be identical to the domain part of the address to pass DMARC. (Nothing in DKIM or DMARC cares about "lrs" vs. "lars". Only your MTA cares when routing the mail.)
Ok, thank you. But then I should have seen someting about the message - to me - in the postfix log. Doesn't that make sence?
That's right. DMARC policy triggers at receipt. Since your address becomes a delivery target only at the delivery from downstream list to your personal address, that's where it would show up. Neither Mailman nor Postfix will refuse to deliver at that point, the policy action is the responsibility of the final recipient. So there will be a local delivery from the downstream list via Postfix to the MX for your subscribed address.
Because "p=quarantine", there will be no delivery failure. Instead, it gets delivered to the last MTA in the chain or an MDA, which then may put it in your INBOX, or may put it somewhere special, typically a spam folder.
If the list's Postfix is also your Postfix, then I'm not sure how Postfix logs receipt, whether it gives the address at receipt, the actual delivered address, or both. Otherwise you should see incoming and outgoing logs for your subscribed address.
The Mailman to outgoing MTA delivery gets obfuscated in Mailman's smtp.log as "delivered to N members" and "posted to M members". Postfix does something similar, I think, in cases where multiple addresses are delivered to the same remote MTA. That is, it only mentions the first of the list of addresses. So that's one reason you might not be seeing your address.
I see that other members, both on annonsering and on medlemmer, does appear in the log, but not lars or lrs for that message.
Does the downstream list personalize delivery? If it does bulk delivery, then you may not see lars@ or lrs@ in the Postfix log. If it's personalized, you should see at least one of them.
