The server that I wrote about earlier (QWEST/USWEST) is saying that the reason they do not allow the approval posts and server requests through is because the server is not approved on the ORBS database (http://www.orbs.org/verify_1.html) I checked the IP address for MITVMA.MIT.EDU, as well as CHERRY.EASE.LSOFT.COM and GRAPE.EASE.LSOFT.COM - which are the relaying servers for the list messages (that do get through to the person having the problems) and the results for the queries look to me to be nearly the same and thus pass their policy. In other words, they should not be being blocked. I'm not exactly sure what an ORBS is and what the database is used for, can somebody enlighten me? Liz Marr
