[mailman3] lmtp error on receiving mails to list #1741

Open jskvbinmv opened 3 months ago

jskvbinmv commented 3 months ago

Hello!

I followed the guide three times to the letter with a new uberspace every time and I have no problem getting everything up and running. I can log in and I get confirmation mails for the admin account (and successfully confirmed my account) and list subscriptions but when I try to send a mail to the list I get the following errors: 

Hi. This is the qmail-send program at caelum.uberspace.de.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<testliste@redacted.uber.space>:

--- Below this line is a copy of the message.`

[...]

Also there is an error in ~/logs/smtp.log

[redacted@caelum logs]$ cat smtp.log

Can anyone point me in the right direction?

Turns out this is the culprit:

https://gitlab.com/mailman/mailman/-/issues/1133

Changing qmail-lmtp as suggested there solves the problem for now. Although this seems to be a workaround at best.

I still see Connection lost during _handle_client() in the log. Don't know if this is a problem or not:
