One of the things some ISPs did in the past was to check that the

the caller was anonymous, some things (like sending mail) could be
disabled. Does she have a permanent "withheld" status on her line?
Can she use webmail to send, or is it only when trying to use the
SMTP facility on Orange (sorry, was Freeserve when I last used
them, and they used to capture port 25 traffic, so I switched
to use Fastmail.fm which allows access on any port, so got onto
their SMTP servers bypassing any block by Freeserve)...
