At last the listserv@uchcecvm is working. It's been a lot hard work. Thanks to Eric who help me a lot. Our mailer system here was incompatible with LISTSERV. It modified the tag of incoming mail. I had to install the COLUMBIA MAILER, make some mods to RSCS, etc. Uf.. I am tired. During the weekend most of the mail that was stack here will be send. One of the reasons that we wanted to install the LISTSERV was to reduce the MAIL traffic between UMDD and UCHCECVM. I never though that we would end distributing mail to some USA nodes. The solution would be to install a LISTSERV at UMDD or to modify the LINK WEIGHTS file. I'll prefer the last one because it wont bother the people at UMDD. (Maybe they don't want to install LISTSERV.) We would like to continue distributing mail to the Chilean nodes also. (UCHCECVM, UCHDCI01, USACHVM1 and soon many more.)
