I updated Yggmail today and immediately noticed that the log is growing a lot due to an error.

sudo journalctl -u yggmail --since today -e

...

How can I prevent him from opening listener on fe80::ab08:a3c0:1ad8:89c?
How can I disable the output of these messages?

It is launched from the systemd unit like this:
yggmail -peer=tcp://192.168.1.15:22854 -database=/home/USER/go/bin/yggmail.db -smtp=192.168.1.15:1025 -imap=192.168.1.15:1143

commented

Do you, by any chance, have another Yggdrasil node on your network with AllowedPublicKeys configured?

commented

No, at the moment Yggdrasil is running on only one device on the home network and Yggmail is running on the same device. AllowedPublicKeys are not used in the configuration file.

commented

Even if I'm launching yggmail like this:
yggmail -peer=unix:///var/run/yggdrasil.sock -database=/home/USER/go/bin/yggmail.db -smtp=192.168.1.15:1025 -imap=192.168.1.15:1143

I get:

One more note...
If you run yggmail like this: yggmail -peer=unix:///var/run/yggdrasil.sock -database=/home/USER/mail/yggmail.db -smtp=192.168.1.15:1025 -imap=192.168.1.15:1143

Every minute the following will be recorded in the log:

What I wrote here earlier is related to Multicast Peer Discovery and I partially figured it out.
I have a couple of questions left, and I will ask them in another "issue".
