We have recently installed the Revised Listserv 1.5n at the University of West Florida. I will try briefly outline some of the symptoms we are experiencing. 1. Mail to the one list (Bitcours) is being forwarded to the subscribers, but some of the subscribers get duplicates of a mailing. For example, one subscriber at NMSUVM1 got his mail from PSUVM and a copy of the same piece of mail from UGA. Two other subscribers (DICKINSN and MUN) also got dupes, although I have not yet heard where their mail came from. Users at Oberlin and IDBSU have stated that they are not getting duplicates. 2. Commands like LIST and HELP are received at the LISTSERV machine from non- local sources (UCF1VM), but receive no reply. Commands like GET LISTSERV FILELIST also do not receive a reply, but the file is transmitted to the user anyway. We are running the Crosswell Mailer X1.25 and it's profile and names files are current. LISTSERV is linked to the MAILER. 3. Mail to the BITCOURS list results in UWF subscribers receiving the mail thru UCF1VM.BITNET (Mailer) when the mail originated here at UWF in the first place. Is this normal ? 4. What role does the BITEARN DISTSUM File play ? 5. Our Stats file for the one list only has stats in the number of mailing column. (we have mail-via=dist2 specified). Thanks in advance, Craig A. Holbert (CRAIG AT UWF) or Jim Webb (JIM AT UWF)
