How can I setup a list so that mail can be accepted ONLY from 1 IP address? As an example I have a list named abc@123.com and it is setup as an announce list only accepting mail from 1 user with an address of bob@123.com.. How can I set this list up so that even if the mail appears to come from bob@123.com the email will post to the list ONLY if bob@123.com's email came from bobspc.123.com which has an an IP address of 123.456.789.246

That's really something that you need to do in your MTA. By the time the message gets to Mailman, we can no longer tell what IP address sent what.

You could set up header_filter_rules (Privacy options... -> Spam filters) for this list as follows:

rule 1

regexps ^Received:.*bobspc\.123\.com ^Received:.*123\.456\.789\.246

action Accept

rule 2 regexp .

Action Discard

However, An easier and better way to do this is to moderate Bob along with everyone else and have Bob post with a header

Approved: password

where password is the list's admin or moderator password.
