bang path
bang path
(communications)...!bigsite!foovax!barbox!me
directs people to route their mail to computer bigsite(presumably a well-known location accessible to everybody) andfrom there through the computer foovax to the account of userme on barbox.
Before autorouting mailers became commonplace, people oftenpublished compound bang addresses using the { } convention(see glob) to give paths from *several* big computers, inthe hope that one's correspondent might be able to get mail toone of them reliably. e.g.
...!seismo, ut-sally, ihnp4!rice!beta!gamma!me
Bang paths of 8 to 10 hops were not uncommon in 1981.Late-night dial-up UUCP links would cause week-longtransmission times. Bang paths were often selected by bothtransmission time and reliability, as messages would often getlost.
