No doubt you have received your share of triple alphabet denoted messages about "services" some purvouers want to draw your attention into. Unfortunately (for the Adaptec driver config symbol name) the AIC7NNN (lets use "wrong" character here to avoid scanners) is considered by weak quality scanners to be the very same as "NNN", which usually is a signature feature in such messages. To understand this, you need to consider how you would detect when the "NNN" is stand-alone, and when it is just part of some other string. See "man perlre" for "\w" and "\W" patterns. Similar kind of content scanner pattern mistakes creep up weekly, if not daily. Sometimes forbidden words lie inside other longer words, sometimes I can't figure out why systems complain about some messages. Some people have asked us (me and DaveM) of why we don't run fully automatic list management (instead of ancient Majordomo 1.x), e.g. a bounce leads into immediate unsubscription. Think about that.. /Matti Aarnio --Yia77v5a8fyVHJSl Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: base64 RkFJTEVEOg0KICBEaWFnbm9zdGljIHRleHRzOg0KICAgICAgPDwtIE1BSUwgRnJvbTo8bGlu dXgta2VybmVsLW93bmVyQHZnZXIua2VybmVsLm9yZz4NCiAgICAgLT4+IDI1MCBDb21tYW5k IE1BSUwgT0sNCiAgICAgPDwtIFJDUFQgVG86PGFuZHJlYXNoYXBwZUBzdWJkaW1lbnNpb24u Y29tPiBOT1RJRlk9RkFJTFVSRSBPUkNQVD1yZmM4MjI7YW5kcmVhc2hhcHBlQHN1YmRpbWVu c2lvbi5jb20NCiAgICAgLT4+IDI1MCBDb21tYW5kIFJDUFQgVXNlciBmb3VuZCBPSw0KICAg ICA8PC0gREFUQQ0KICAgICAtPj4gMzU0IENvbW1hbmQgREFUQSBTdGFydCBtYWlsIGlucHV0 OyBlbmQgd2l0aCA8Q1JMRj4uPENSTEY+DQogICAgIDw8LSAuDQogICAgIC0+PiA1NzAgTUZp bHRlciAobGluZSAyMDogY29udGVudCBleGNlcHRpb24pDQpGQUlMRUQ6DQogIERpYWdub3N0 aWMgdGV4dHM6DQogICAgICA8PC0gTUFJTCBGcm9tOjxsaW51eC1rZXJuZWwtb3duZXJAdmdl ci5rZXJuZWwub3JnPiBCT0RZPThCSVRNSU1FIFNJWkU9MjE1Mw0KICAgICAtPj4gMjUwIDIu MS4wIDxsaW51eC1rZXJuZWwtb3duZXJAdmdlci5rZXJuZWwub3JnPi4uLiBTZW5kZXIgb2sN CiAgICAgPDwtIFJDUFQgVG86PGV2YW5AdGhldW5peG1hbi5jb20+IE5PVElGWT1GQUlMVVJF IE9SQ1BUPXJmYzgyMjtldmFuQHRoZXVuaXhtYW4uY29tDQogICAgIC0+PiAyNTAgMi4xLjUg PGV2YW5AdGhldW5peG1hbi5jb20+Li4uIFJlY2lwaWVudCBvaw0KICAgICA8PC0gREFUQQ0K ICAgICAtPj4gMzU0IEVudGVyIG1haWwsIGVuZCB3aXRoICIuIiBvbiBhIGxpbmUgYnkgaXRz ZWxmDQogICAgIDw8LSAuDQogICAgIC0+PiA1NTAgNS43LjEgR28gYXdheSBzcGFtbWVyDQpG QUlMRUQ6DQogIERpYWdub3N0aWMgdGV4dHM6DQogICAgICA8PC0gTUFJTCBGcm9tOjxsaW51 eC1rZXJuZWwtb3duZXJAdmdlci5rZXJuZWwub3JnPiBCT0RZPThCSVRNSU1FIFNJWkU9MjE1 Mw0KICAgICAtPj4gMjUwIDIuMC4wIGxpbnV4LWtlcm5lbC1vd25lckB2Z2VyLmtlcm5lbC5v cmcgT0sNCiAgICAgPDwtIFJDUFQgVG86PGFkZGVyZEB3bW9sLmNvbT4gTk9USUZZPUZBSUxV UkUgT1JDUFQ9cmZjODIyO2FkZGVyZEB3bW9sLmNvbQ0KICAgICAtPj4gMjUwIDIuMC4wIGFk ZGVyZEB3bW9sLmNvbSBPSw0KICAgICA8PC0gREFUQQ0KICAgICAtPj4gMzU0IFJlYWR5IGZv ciBkYXRhDQogICAgIDw8LSAuDQogICAgIC0+PiA1NTQgRmlsdGVyZWQgb3V0IGJ5IEZpbHRl ciAwIGJlY2F1c2UgIlN1YmplY3QiID0gIlJlOiBBSUM3WFhYIDYuMi41IGRyaXZlciINCg0K Rm9sbG93aW5nIGlzIGNvcHkgb2YgdGhlIG1lc3NhZ2UgaGVhZGVycy4gT3JpZ2luYWwgbWVz c2FnZSBjb250ZW50IG1heQ0KYmUgaW4gc3Vic2VxdWVudCBwYXJ0cyBvZiB0aGlzIE1FU1NB R0UvREVMSVZFUlktU1RBVFVTIHN0cnVjdHVyZS4NCg0KUmVjZWl2ZWQ6IChtYWpvcmRvbW9A dmdlci5rZXJuZWwub3JnKSBieSB2Z2VyLmtlcm5lbC5vcmcgdmlhIGxpc3RleHBhbmQNCglp ZCA8UzI5MjM4NEFiU0JVTjdqPjsgVGh1LCAyMSBGZWIgMjAwMiAwODo1OTozOSAtMDUwMA0K UmVjZWl2ZWQ6IChtYWpvcmRvbW9Admdlci5rZXJuZWwub3JnKSBieSB2Z2VyLmtlcm5lbC5v cmcNCglpZCA8UzI5MjM4NUFiU0JVTjczPjsgVGh1LCAyMSBGZWIgMjAwMiAwODo1OToyOSAt MDUwMA0KUmVjZWl2ZWQ6IGZyb20gbnMudmlydHVhbGhvc3QuZGsgKFsxOTUuMTg0Ljk4LjE2 MF06ODIwOCAiRUhMTyB2aXJ0dWFsaG9zdC5kayIpDQoJYnkgdmdlci5rZXJuZWwub3JnIHdp dGggRVNNVFAgaWQgPFMyOTIzODRBYlNCVU43Uz47DQoJVGh1LCAyMSBGZWIgMjAwMiAwODo1 OToxOCAtMDUwMA0KUmVjZWl2ZWQ6IGZyb20gYnVybnMuaG9tZS5rZXJuZWwuZGsgKFsxOTIu MTY4LjAuMl0gaWRlbnQ9bWFpbCkNCglieSB2aXJ0dWFsaG9zdC5kayB3aXRoIGVzbXRwIChF eGltIDMuMzQgIzEpDQoJaWQgMTZkdGtMLTAwMDNxdi0wMDsgVGh1LCAyMSBGZWIgMjAwMiAx NDo1ODo1NCArMDEwMA0KUmVjZWl2ZWQ6IGZyb20gYXhib2UgYnkgYnVybnMuaG9tZS5rZXJu ZWwuZGsgd2l0aCBsb2NhbCAoRXhpbSAzLjM0ICMxKQ0KCWlkIDE2ZHRrRS0wMDAzcnUtMDA7 IFRodSwgMjEgRmViIDIwMDIgMTQ6NTg6NDYgKzAxMDANCkRhdGU6CVRodSwgMjEgRmViIDIw MDIgMTQ6NTg6NDYgKzAxMDANCkZyb206CUplbnMgQXhib2UgPGF4Ym9lQHN1c2UuZGU+DQpU bzoJQWxhbiBDb3ggPGFsYW5AbHhvcmd1ay51a3V1Lm9yZy51az4NCkNjOglDYXJsbyBTY2Fy Zm9nbGlvIDxzY2FyZm9nbGlvQGFycGFjb29wLml0PiwNCglsaW51eC1rZXJuZWxAdmdlci5r ZXJuZWwub3JnLCAiSnVzdGluIFQuIEdpYmJzIiA8Z2liYnNAc2NzaWd1eS5jb20+DQpTdWJq ZWN0OiBSZTogQUlDN1hYWCA2LjIuNSBkcml2ZXINCk1lc3NhZ2UtSUQ6IDwyMDAyMDIyMTEz NTg0Ni5HQTE0NjM0QHN1c2UuZGU+DQpSZWZlcmVuY2VzOiA8MjAwMjAyMjEwNzUyNTMuR0gy NjU0QHN1c2UuZGU+IDxFMTZkdG12LTAwMDZ6Mi0wMEB0aGUtdmlsbGFnZS5iYy5udT4NCk1p bWUtVmVyc2lvbjogMS4wDQpDb250ZW50LVR5cGU6IHRleHQvcGxhaW47IGNoYXJzZXQ9dXMt YXNjaWkNCkNvbnRlbnQtRGlzcG9zaXRpb246IGlubGluZQ0KSW4tUmVwbHktVG86IDxFMTZk dG12LTAwMDZ6Mi0wMEB0aGUtdmlsbGFnZS5iYy5udT4NClNlbmRlcjoJbGludXgta2VybmVs LW93bmVyQHZnZXIua2VybmVsLm9yZw0KUHJlY2VkZW5jZTogYnVsaw0KWC1NYWlsaW5nLUxp c3Q6CWxpbnV4LWtlcm5lbEB2Z2VyLmtlcm5lbC5vcmcNCg0K --Yia77v5a8fyVHJSl--
