Dear all,
a) I have a very strange problem with postfix, it worked for more than
one year without problem, and now, for about one month some incoming
emails started to fail in the night (approx. between 4AM and 5AM) but
not every day, with errors like :
* Out: 451 4.3.0 <em...@domain.ch>: Temporary lookup failure
* Out: 451 4.3.0 Error: queue file write error
It's very strange for me, therefore any help on that subject would be
greatly appreciated !
b) I found this interesting link, but it doesn't contain a solution, it
just says "sending server will anyway retry later" :
http://flakshack.com/anti-spam/wiki/index.php?page=Queue+File+Write+Errors
c) More info :
That's what I see in the logs approximately at the same time these
errors are seen :
