Here are some Fridays. Ignore the "rejected by ruleset" column;
I added a bunch of rules to it Oct 9. The "total mails undelivered"
column tells the tale -- the more so, now that the virus count column
is negligible.
Mails spamassassin rejected scanner total mails
Total says 'spam' by ruleset says virus undelivered
Oct 10 5534 1221 (22.06%) 952 (17.20%) 47 ( 0.85%) 2220 (40.12%)
Oct 3 6007 1930 (32.13%) 309 ( 5.14%) 56 ( 0.93%) 2295 (38.21%)
Sep 26 6214 2109 (33.94%) 304 ( 4.89%) 75 ( 1.21%) 2488 (40.04%)
Sep 19 6373 1966 (30.85%) 373 ( 5.85%) 158 ( 2.48%) 2497 (39.18%)
Sep 12 5478 1760 (32.13%) 333 ( 6.08%) 13 ( 0.24%) 2106 (38.44%)
Sep 5 5555 1450 (26.10%) 447 ( 8.05%) 363 ( 6.53%) 2260 (40.68%)
The "undelivered" fraction appears to be roughly constant over the 6
Fridays in this sample, but it has been rising over the past several
months.
Those not familiar with the story of "Nadine" should have a careful
look at Michael Rathbun's site
<http://www.honet.com/Nadine/default.htm>
or one of its mirrors for a tale of Things Gone Horribly Wrong.
Another of his sites, <http://www.tesp.com/tespUBErate.htm>,
shows spam rates there over the past 30+ months, and should
prove both instructing and horrifying.
