basically what happened is that the sf listserver tries to verify that
the sending domain and system is valid. Besides other things it tries
to use Postmaster as a recipient. Instead of answering 250 'ok' the
mail server of your ISP says 550 'No such user here', which is in
violation of rfc 2821 section 4.5.1 :
------------
Any system that includes an SMTP server supporting mail relaying or
delivery MUST support the reserved mailbox "postmaster" as a case-
insensitive local name. This postmaster address is not strictly
necessary if the server always returns 554 on connection opening (as
described in section 3.1). The requirement to accept mail for
postmaster implies that RCPT commands which specify a mailbox for
postmaster at any of the domains for which the SMTP server provides
mail service, as well as the special case of "RCPT TO:<Postmaster>"
(with no domain specification), MUST be supported.
------------
The only thing you can do is asked tiscali to fix their mailserver
configuration, basically adding the valid postmaster accounts needed,
according to rfc 2821.
Unfortunately we can not do much to help as this is mainly a problem
of tiscali.

starting point for sf mail problems.
