good so far, but I will report back in a couple more days...
I wanted to mention that there are some in this posting that
are recommending greylisting... but have not said anything
about how this is implemented into sendmail... so, what is
your take on this?
Thanks-
Dan
Some are strong proponents - I am not - in part as I have no real
world experience on a real server in part because I believe while it may
work well, I dont like the collateral damage.
With GreetPause I am already causing a small delay which works very
well for those spammers/bots which are in violation of the standards.
However, I have carefully singled out all major email MX outbound hosts
for 0 greet pause. But greet pause is an SMTP delay waiting not a
rejection as gray listsing does. Graylisting leaves the mail delay in
the hands of the other end - I prefer the control in my hands.
I want email coming through fast - when I'm on the phone with someone
and they say i just sent you the xxx .. i dont want to wait for it.
Just my view -though with work graylisters should/could/and likely do
whitelist all relevant major isp's - I am not an advocate and on the
servers I control, I do not use it.
