Reading also James Wilkinson's comments ("the list administrators tried
putting per-subscriber data in the subject of a non-list e-mail sent to
all subscribers, and got nothing back...") I understand now that this is
not an easy problem to solve. I'm not experienced in list admin stuff at
all but could this potentially work? A script that disables mail
delivery to all list subscribers except subscriber <n> and send out an
email to the list. Wait for the uol.com.br response. If it isn't
received, disable mail delivery for subscriber <n>, enable mail delivery
for subscriber <n+1> and send out the message again. Rinse and repeat
until success.
Alternatively the powers that be could stick uol.com.br in every RBL on
the planet and see if that gets their attention :)
