I recently changed ISP, and shortly thereafter I began to get complaints
that emails sent to me were being bounced.
The reason for this turned out to be that the ISP was using a crude
rejection system, so that any sender IP found on anti-spam blacklists were
simply rejected with no notification to the intended recipient.
My email setup works by having a single destination of my own domain,
emails being redirected according to address (e.g.
(E-Mail Removed),
(E-Mail Removed)) from there to where I actually want them. This is so that
when I change ISP (and email provider) I don't have to make any changes to
my stationery, or tell people to change their address books. The forwarding
provider had got itself on one of these lists (it is now removed, after I
told them of the problem).
There was no way to opt out of this Draconian filtering, this was the
default. After kicking up a fuss, I now have (for a fee!) a bypass so that
my eail doesn't suffer in this way.
It is also easy for Big Brother to manipulate the listings, to get
politically sensitive sources effectively blocked from communicating with
their sympathisers. Frightening.
So beware of this over-simple system, which suits ISPs and governments
because it is easy to implement and manipulate, but is not particularly
good for users who are savvy enough to handle their own email systems.
Check it out BEFORE changing ISP.
