The mailing list for listmasters using Sympa

[Rodrigo Filgueira <address@concealed>]

Hi there, another question ...
Hotmail considers mail sent from our sympa server as potentially 
unwanted mail.
Do you have any idea why that may be? we are not spammers we host lists 
for distance learning in specific subjects and our lists do not have 
more than 300 addresses ...

any ideas on why this happens and how to revert it?
tia
