To be diagnosed and done in a few hours max.
The error is that wiadodmessages are suddenly queued. For many years everything was fine.
Perhaps something happened in mail settings, because there was a change of domain to another and in a moment the default name returned.
However, before or now there were also such messages, but now no messages arrive at all and have this message mailer-deamon:
this is the mail system at host example.pl. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message.
