I respect you, but I feel sorry here. Tarpit and slowdown are know since
a long time, so mailchannel bring nothing here (except marketing). In
particular,"greet pause" has been implemented by some people. the fact
that this is not common is not due to an implementation difficulty, but
to the fact that the cost/benefit ratio is not very interesting.
To be fair (I'm testing it right now): It's easy to get running.
Right now the Tarpit and slowdown features cannot be had in Postfix,
so I'm giving it a spin.
you can use sleep. sure, it stops the process, but if your system is not
under heavy load, it may be acceptable...
but anyway. I don't see what mailchannel are bringing that deserves this
debate. it looks to me like this:
- they started trying to sell greeetpause. and it didn't work enough
- they moved to "slowdown" and they're trying to talk about
In both cases, they don't provide any serious study. they only show
numbers that go with their claims. I don't know for others, but my logs
don't seem to confirm theirs.
and the slowdown thing is based on the theory that spammers have better
things to do than wait. now that we know more about botnets, this theory
doesn't stand.
how long would it take to write an asynchronous smtp client?
