If you still receive legitimate mail from such servers, then no.  But I
believe most of the major service providers already started doing this
some time ago at the ISP level, so you wouldn't receive this mail to
begin with.

For consumer-grade DSL/cable services, AFAIK it's next to impossible to
convince them that any legitimate need to allow such mail would outweigh
the potential for spam.

Lots of sites will.  People running mail servers from dynamic IPs will
have better luck configuring their MTAs to use their ISP's SMTP server
as a smart host for outgoing mail.
