Hi there, Quick question about this error I saw in the logs just now. There is a note about it on Ralf's page [ http://www.arschkrebs.de/postfix/postfix_unknown.shtml ], but I am trying to work out if its a problem or not caused by my postfix implementation. The server really has no load. Its idle. After the connect from unknown [unknown], mail reception continued as usual.
One change was made to-day, and was the activation of dkim-filter for before and after queue processing, although the dkim-filter has been running fine for the past 5 hours. I would like to know whether the problem is my end or its a client being naughty. Best wishes, S.
