Sending mails from dynamic IP addresses without using the
ISP's mail server is not "normal".

That's not true in general.  It depends which blacklist
you use.  There are indeed very "aggressive" blacklists.
I don't recommend to use one of those.

Personally I've the following two lines in my sendmail.mc
which work very well.  And yes, I can still receive mails
from google, yahoo etc.  :-)

FEATURE(dnsbl,`combined.njabl.org',`Message from $&{client_addr} rejected - see http://njabl.org/')
FEATURE(dnsbl, `list.dsbl.org', `Rejected mail from $&{client_addr} - see http://dsbl.org/')dnl
