Below is the log which I happened to be watching with a tail -f. Is this an anti-greylisting strategy? It continued for the full 5 minutes that I have greylisting set for and then it was gobbled by Spam Assassin so I don't suppose it really matters. I wonder if it would continue for hours if I had greylisting set up like that. Hmm, I just noticed that it started 3 minutes after the first attempt and then it was continuous for the full 5 minutes. One thing I find slightly disconcerting is that the number in square bracket was the same for the whole 5 minutes, viz [13989]. I assume this is the sendmail process id and I should have thought it would be different for each attempt?
