I'm not sure I understand the issue here. spamdyke (and qmail) don't
check the _sender's_ domain against the rcpthosts file, they only check
the _recipient's_ domain. If you could configure spamdyke (or qmail) to
block senders that weren't hosted on your mail server, you would never
receive any email from anyone outside your own domain(s). Is that
really what you want?
In any case, spamdyke allows authenticated senders to bypass all of its
filters, under the assumption that authentication implies authorization
to send anything. If you really want to ignore authorization and block
senders from domains that aren't hosted locally, you could do something
like this (BEWARE, I haven't tested this configuration myself):
First, tell spamdyke to block authentication attempts so no one can
authenticate.
smtp-auth-level=none
Next, blacklist everyone:
ip-blacklist-entry=0.0.0.0/0.0.0.0
Then create a copy of your rcpthosts file and edit it to put the "@"
character at the start of every line, before the domain name.
Next, use that modified file as a sender whitelist file (assuming
you named it /var/qmail/control/rcpthosts.whitelist.txt):
sender-whitelist-file=/var/qmail/control/rcpthosts.whitelist.txt
Be sure to use the "local-domains-file" and "access-file" options so
spamdyke override qmail's relay filter. Otherwise your whitelisted
senders won't be able to send mail to anyone outside your domain(s).
Good luck.
