hey, sending mail won't completely work for me... it keeps saying for certain recipients "cannot send mail. the recipient "firstname.lastname@example.org" was rejected by the server." im using NYU mail. if i send an email to myself (or other NYU addresses) it seems to work, but if i send an email to any other ISPs (i've tried three) i get the error message above. this is while using the EDGE network. any ideas?? thanks!
