My customers who reach me (a mail service) from Earthlink dialups are
affected by this. Apparently it's still happening. I run a listener on
another host and port, known only to this (so far) small subset of people,
to be able to serve them. In general, we advise people to use their ISP's
relay for outgoing mail, but Earthlink won't let them relay because the
sender domain is not one that Earthlink knows about (i.e. is charging them
for). Apparently.
In principle, I endorse this practice. It seems to reduce abuse, which is
all to the good. But in practice, it creates a problem I have to solve.
Is there a way for these unfortunate people to register other domains with
Earthlink as "outbound relay only"?
