Hi,

I am trying to whitelist a firend, so I get emails quicker from him. 

The command I use is:

    cd /opt/iredapd/tools
    python spf_to_greylist_whitelists.py sbcglobal.net

I have not had success whitelisting his domain.
from /etc/log/maillog:  (I changed my domain to xx.com, and his email address to yy)

Pinging sbcglobal returns no data (so I suspect this might be the problem), and I have tried to whitelist yahoo.com and att.net, because I think they bought sbc.   Still no luck.

The spf_to_greylist_whitelists.py command seems to work for other email domains I have whitelisted, (bestbuy.com, costco.com, etc). 

How can I determine what domain to whitelist?

Thanks,
Dave
