What do you mean that the process hangs?

Regarding the warning you're seeing, the ARC sealer uses the signature for your default domain, probably you removed rsa-test1.lt and did not update your new default domain. This can be done from the webadmin under https://your.server/settings/report/edit. Or if you prefer to use a different signature for ARC sealing you can change it from https://your.server/settings/arc/edit.

Regarding default domain your were right, there was old domain name in https://your.server/settings/report/edit.

But mail server still hung every time on incoming SMTP session. Alter that Web-based admin is not responsive, email does not get stored to database. This is the only related record: 2024-05-30T14:39:47.821221Z INFO session{instance="smtp" protocol=Smtp remote.ip="209.85.161.54" remote.port=56643}: common::listener::listen: context="tls" event="handshake" version=TLSv1_3 cipher=TLS13_AES_256_GCM_SHA384

When trying to restart systemd service, it does not stop clearly:

May 30 17:47:52 smtp1 systemd[1]: Stopping stalwart-mail.service - Stalwart Mail Server Server...

Email sending does work as expected.

Have you perhaps installed version of 0.8.1 before it was officially announced? During the build process a very similar bug was found that was corrected and then a new binary was compiled followed by the official announcement. Just to be sure update the binary to the latest version.
