is rumored to have said:
I don't think someone can drop almost all mail and still call itself a mail
server.
Were you running a mail system in the early-mid 2000s?
At that time, I tracked the performance of a mid-sized spam control system
for a business that handled around a million inbound SMTP sessions per day.
The proportion of mail we rejected as spam was persistently over 90%, and at
times broke 98%. We never had a significant FP problem.
Although the server I ran at that time did listen to the whole internet,
our MX pointed at a service that spared me from much of that spam,
though I was aware of it and knew the folks stopping it for me.
The state of email is better today,
That is a surprise to hear. Reading this list has given me the impression
that the spam volume is worse now than it was then. Spamming is a much bigger
business now and the internet is faster, so I would have thought spammers
would be sending more messages, even compared to the increase in legitimate
email.
If they are sending comparatively fewer messages I can only imagine
that is because their strike rate is better, which is *more* worrying.
What have I misunderstood ?
but I wouldn't be at all surprised if some sites still have a 90%+
spam burden.
