Fwiw: I recently saw this kind of behaviour on Oracle on a Solaris host:
Some mailhost is configured for "smtp_out_server", which is supposed to
be used for utl_mail (pl/sql), but is also used for utl_smtp (ignoring
the hostname passed to utl_smtp.Open_Connection(...).)

I haven't used JavaMail myself, so can't say much about that.
