W0llys Posted May 20, 2006 Share Posted May 20, 2006 And yes the ISP ought to inform its subscribers that it is using a bl to block email. However, typical ISPs don't have good communication skills, it seems to me. If they told their users in the right way, the users would be enthusiastic. But they think that all end users are ignorant, uneducable doofuses and won't understand the value of blocklists because they won't read the information carefully and will just complain. Hey! At last someone that at least partially agrees with me, on some points! Bonus smiley awarded! A new question: Does anyone have any statistics? What is the ratio (actual or estimated) of spam to legitimate mail when a service like yahoo/gmail is blacklisted? As I understand, gmail (or yahoo) can only be blacklisted *itself* when the users are using the web interface (or perhaps some API?) to send spam. Is this the common way of sending spam through these servers, or is it more common to use SMTP? It would be interesting to see some numbers on the amount of spam coming from different sources - open relays, hacked servers or mail scripts, zombies, 'rogue' sites, and web mail services like yahoo, gmail and hotmail. senderbase.org tell give me the following stats for web27705.mail.ukl.yahoo.com Volume Statistics for this IP Magnitude Vol Change vs. Average Last day 4.7 1730% Last 30 days 3.9 235% Average 3.4 Does this mean that it has been a 17-fold increase from average for this IP and that the spam:legitimate ratio - if the increase is only spam - must be something like 17:1 (which I would agree would make it a strong candidate for blocking..)?
