Today we had a 'relaying denied' issue between 15:08-17:02 p.m. Here it is the output of pflogsumm:

It happened the same for Yahoo, Hotmail, GMail and others. But, according to the above table, it seems, just some of them were bounced, weren't they? I wonder what happened. Could somebody please give me an answer about what could have happened?
