We recently upgraded SENDMAIL ... with no apparent adverse affects. Then, at the end of March, we upgraded the Linux system. My systems programmer gives me these number for new levels: sendmail RHL 7.3 system ... RHL sendmail 8.11.6 with backported security and lsoft patches glibc 2.2.5-43 The symptoms are hundreds of files in the LISTSERV spool directory and people complaining that mail from LISTSERV is not arriving. The relevant portion of my go.user contains SORT_RECIPIENTS=1 TZONE=`date +%z` export TZONE MAXBSMTP=50 export MAXBSMTP SMTP_RESET_EVERY=60 export SMTP_RESET_EVERY SMTP_FORWARD_1="2*MURDOCH.UNET.MAINE.EDU" export SMTP_FORWARD_1 "Murdoch.unet.maine.edu" is the local "lists.maine.edu" LISTSERV system. LISTSERV has not been changed in months. The only thing I notice in listserv.log is at startup: Currently processed 10 files. Currently processed 20 files. ... Currently processed 1160 files. Currently processed 1170 files. 3 Apr 2003 23:58:09 SIGNUP files are being compressed... 3 Apr 2003 23:58:09 -> 7 entries removed. 3 Apr 2003 23:58:09 Nearest NJE host is LISTSERV@CUNYVM ... (Now there are 2300+ files waiting) My systems programmer, in a quick look at his sendmail logs, says that he thinks he is seeing just one 50-recipient mail on the couple of posts that we tracked ... that should have passed several 50-recipient items. If I look in spool for one post, I see about 15 awaiting files with various recipients, consecutively numbered. The first recipient in the oldest mail is "[log in to unmask]" which to me suggests there was another .mail file that had been processed. Any suggestions? Does this sound familiar? -- Wayne T.
