Comcast Port 25 Blocks Result In Less Spam
Dozix007 writes "Ars Technica reports that: 'After Comcast finally owned up to the massive amounts of spam coming from
their network, they decided to identify spammers and zombie relays on their
network and block
port 25 traffic from those IP addresses. Comcast's efforts are starting to
pay off. They announced the amount of spam from their network has dropped
35 percent since they began port blocking and
traffic estimates from SenderBase seem to confirm the claims. Spam coming
from Comcast subscribers who were formerly on AT&T networks also
seems to have decreased'."
Now does the mailserver "Provided by your ISP work? No, they block any IP not their own. Now if port 25 wasn't blocked you could use your own and avoid having to change the Client setup.
I have exactly this problem and have to pay $10 / year to have access to a smtp server that will allow me to log-in from any IP.
