Sorry to disturb you again. Since around two weeks we have
massive DNSBL response time problems at our US site.
I can confirm that the Network itself works correctly but we have
a lot of customer who complains about following error message :
----- Transcript of session follows -----
.. while talking to s*******y.s***a.com
<<< 550 Rejected due to DNSBL server response (dnsbl.cobion.com - 126.96.36.199)
.. connection error: connection reset by peer/timeout
Only the US Protector is affected. Connection from CH looks very fine.
Is there an IBM DNSBL Server in the US that we can use?
Many thanks for all your input!
