 This looks to me as if the hostname that sendmail is reporting when it
connects to another host is not it's "real" - i.e. Internet registered -
host name.

you could try enabling the following line in sendmail.mc
define(`SMART_HOST',`smtp.your.provider')

This should pass all external emails through to your ISP's mail host for
delivery. They may accept the connection based solely on your email address.


If that doesn't work, you'll need to enable the "MASQUERADE_DOMAIN" option
to replace your Internal domain name with your Internet legal external
domain name.

Don't forget to run `make -C /etc/mail' to rebuild the sendmail.cf, and
`service sendmail restart' to ensure that the new version is used.
