Mail admins usually treat non-MTA software that send email as highly
potential sources of spam. In your case, a whitelisting arrangement
would take care of the problem or whatever arrangement they may have.
Properly managed ISP's/domains will have a reachable contact at
postmaster at ISP/domain.
The third party component set you mentioned...is it the original of
The Indy 9 component most probably got itself into blacklists because of
the IntraWeb framework, which most probably uses Indy 9 for smtp, has
inadequate measures against abuse and the Indy 9 component creates an
easily identifiable header.
Whole server farms running proper MTA software will get blacklisted if
they have abusable scripts or other stuff using them.
