Hmm, It could have something to do with earthlink using what appears to
be a round-robin DNS structure for 'smtp.earthlink.net'.  Do a 'dig
smtp.earthlink.net' and see how many A records they have listed for that
name.   Do a 'dig -x' on the dotted-quad IP and see that they dont
resolve back to smtp.earthlink.net.

If the ALE mailing list looks at Received-From and not From:, that could
be causing an issue.  I believe there's an option you cant send the ALE
list daemon to allow you to post from a different address than you
receive at, that may help you out.

Also note that FEATURE(accept_unresolvable_domains) opens you up to
receiving spam from the particularly clueless spam hosts.  Also, note
that commenting out the FEATURE(genericstable) isn't going to have an
effect.  m4 is a strings-based parser (thusly why you need a "dnl" on
the end of everything), so if it finds a keyword (in this case,
FEATURE), even if it's preceeded by a #, it's going to parse it into the
cf file you generate.

You might also want to try FEATURE(masquerade_envelope)dnl to masquerade
the envelope as well as the header addresses.

you might want to enclose the second argument in `'.  (note the
backtick)

you may not need this set, since you're masquerading as earthlink.net
anyways.

Just some thoughts.
