You may prefer it but the target doesn't. That's why your email is
being blocked.

"For some reason"? Give us your IP address and we'll tell you why.
There's a good chance that you're in a dynamic IP address range and that
will be blocked by a LOT of hosts.

I don't think so. SMTP doesn't have an error for "we don't like your
source address". The transaction is being rejected but you really don't
know why - different servers reject with different messages and error
codes.
What you can do with sendmail is to add mailertable entries for specific
domains that will override the default smart host.
Personally, I gave up and send all email through my ISP.
