problem with AOL addresses
I sent a query to the list and it went out, but the message going
through AOL bounced:

This problem apparently is not new (from 2000: "Ist das Dreist oder
was?") but it has hit me only in the last couple of weeks.
Apparently, in a clumbsy (everyone seems to agree) effort to block spam, AOL does a reverse DNS
lookup, which fails when the sender's IP address is dynamic (no mx
record). On the other hand, it has been suggested that AOL is simply filtering access
to certain ranges of cable and DSL IP addresses.
I suspect there are enormous numbers of people using dynamic IP
addresses, and so it may be that many list subscribers who have AOL as
their ISP are missing mail. Is this so? Anyone else experiencing this
difficulty?
Can anyone shed some light on this? Is there a reasonable work
around. Does one have to relay one's mail?
