Joanne,

This pretty much looks like the faulty message is in the
pop.earthlink.net account rather than the dslextreme.com, and I haven't
seen configuration or verbose logging of the earthlink polls yet in this
thread, unless I am overlooking something... and Postfix is right to
reject the mail address, it is outside the permitted syntax for MAIL
commands per the BNF syntax in RFC-5321 (page 41 bottom/42 top - in
prose that specifies that the hyphen cannot be head or tail of a
sub-domain part, but must be surrounded by "letter or digit").

The log message incomplete stems from the log "reading message" that
gets interrupted by the 501 5.1.7 error, logging makes this excursion,
and finally the "not flushed" concludes the original log message.

HTH
