My site activity level is rather low, so I can't say if we're suffering any due to x-spam traffic or not. I also don't know if the distribution of incoming jobs is uniform or not, among sites (in other words, is it "expected" that I would see every one that you see?). For what it's worth, here is a list of the daily total of x-spam jobs logged here. In 198 observations, 43 days averaged less than one per minute; 77 days averaged more than 2 per minute; 10 of the 77 averaged more than 3 per minute. I haven't counted the "recognized spam" traffic. 20050501 : 1404 20050502 : 1714 20050503 : 3892 20050504 : 3562 20050505 : 7520 20050506 : 6378 20050507 : 6142 20050508 : 4086 20050509 : 2415 20050510 : 5938 20050511 : 3190 20050512 : 8014 20050513 : 6464 20050514 : 4128 20050515 : 1968 20050516 : 2108 20050517 : 8144 20050518 : 2858 20050519 : 2952 20050520 : 3464 20050521 : 3878 20050522 : 5805 20050523 : 1626 20050524 : 9082 20050525 : 7436 20050526 : 5732 20050527 : 8044 20050528 : 11120 20050529 : 6194 20050530 : 1754 20050531 : 1634 20050601 : 3017 20050602 : 4091 20050603 : 2510 20050604 : 1380 20050605 : 4872 20050606 : 2909 20050607 : 2687 20050608 : 5494 20050609 : 2132 20050610 : 1054 20050611 : 732 20050612 : 2304 20050613 : 2062 20050614 : 6458 20050615 : 5754 20050616 : 5308 20050617 : 7342 20050618 : 5604 20050619 : 2488 20050620 : 2424 20050621 : 5886 20050622 : 6056 20050623 : 3278 20050624 : 5618 20050625 : 1530 20050626 : 1858 20050627 : 1508 20050628 : 3675 20050629 : 3264 20050630 : 2008 20050701 : 10386 20050702 : 3180 20050703 : 3836 20050704 : 2318 20050705 : 2080 20050706 : 2026 20050707 : 3458 20050708 : 2200 20050709 : 1264 20050710 : 416 20050711 : 2144 20050712 : 6578 20050713 : 6464 20050714 : 1222 20050715 : 1608 20050716 : 3382 20050717 : 2414 20050718 : 2518 20050719 : 2048 20050720 : 2208 20050721 : 2672 20050722 : 1508 20050723 : 3910 20050724 : 1452 20050725 : 2446 20050726 : 3512 20050727 : 3836 20050728 : 1564 20050729 : 1181 20050730 : 836 20050731 : 808 20050801 : 1520 20050802 : 2322 20050803 : 948 20050804 : 3042 20050805 : 2796 20050806 : 1700 20050807 : 1478 20050808 : 3986 20050809 : 1224 20050810 : 1240 20050811 : 3272 20050812 : 1938 20050813 : 2226 20050814 : 1992 20050815 : 3288 20050816 : 8224 20050817 : 1412 20050818 : 1038 20050819 : 1132 20050820 : 1648 20050821 : 2048 20050822 : 978 20050823 : 1536 20050824 : 1746 20050825 : 1159 20050826 : 1588 20050827 : 1190 20050828 : 1156 20050829 : 1686 20050830 : 2212 20050831 : 1638 20050901 : 1684 20050902 : 2038 20050903 : 816 20050904 : 1184 20050905 : 3850 20050906 : 1178 20050907 : 1028 20050908 : 928 20050909 : 1112 20050910 : 458 20050911 : 764 20050912 : 4848 20050913 : 6960 20050914 : 4628 20050915 : 4298 20050916 : 920 20050917 : 746 20050918 : 1136 20050919 : 1478 20050920 : 4174 20050921 : 1486 20050922 : 1832 20050923 : 2932 20050924 : 1306 20050925 : 1932 20050926 : 4660 20050927 : 3078 20050928 : 1298 20050929 : 3080 20050930 : 2356 20051001 : 918 20051002 : 1706 20051003 : 4650 20051004 : 2362 20051005 : 1924 20051006 : 1698 20051007 : 1666 20051008 : 948 20051009 : 1340 20051010 : 2270 20051011 : 3334 20051012 : 1812 20051013 : 3770 20051014 : 6940 20051015 : 646 20051016 : 1880 20051017 : 6476 20051018 : 2264 20051019 : 4162 20051020 : 2356 20051021 : 1304 20051022 : 3050 20051023 : 962 20051024 : 3282 20051025 : 4776 20051026 : 1126 20051027 : 1602 20051028 : 1560 20051029 : 1582 20051030 : 2754 20051031 : 2202 20051101 : 1824 20051102 : 1920 20051103 : 1240 20051104 : 1650 20051105 : 1708 20051106 : 7056 20051107 : 1656 20051108 : 5280 20051109 : 1470 20051110 : 6052 20051111 : 1310 20051112 : 2434 20051113 : 1298 20051114 : 3526 >>> [log in to unmask] 11/14/2005 8:57:44 PM >>> Once upon a time, X-SPAM notifications served a useful purpose, because spammers set up jobs to send thousands of messages with the same sender address. The world has moved on, spammers techniques have changed, and the X-SPAM jobs have become less than useless: they have become spam. The volume of X-SPAM jobs which our LISTSERV server receives from other LISTSERV servers is significantly higher than the volume of actual spam which our LISTSERV server receives. This has become a major performance issue. Despite L-Soft's claims that web requests take precedence over inbound messages in the listserv/spool directory, we continually experience web performance problems during periods of high inbound mail volume, and most of those messages seem to be X-SPAM jobs from other LISTSERV servers. Are we the only site experiencing these problems? -- Paul Russell Senior Systems Administrator OIT Messaging Services Team University of Notre Dame
