451 Message temporarily deferred - 4.16.50
probably they are just overloaded.
Several of my biggest clients report huge increases in spam in the
last couple weeks.
I have one new client whose Barracuda was so overwhelmed taking 10+
hours to pass messages through it, so we put an IMGate out front,
which blocks 80% of inbound with only a couple of filters. IMGate is
delivering less that 2000 msgs/hour to Barracuda now while blocking
about 7K/hour.
Barracuda is STILL working on 5000 msgs in its queue. IMGate averages
20 secs to deliver a msg to the Barracuda, when it should average way
under 5 secs, which indicates how slowly the Barracuda is running.
