I have a qmail server running on RH7 w/ tcpserver. I has been installed for about 2 weeks. For about a week it ran fine but it suddenly started to time out forwarding mail both to internal addresses and to external addresses. I researched the list and assumed it was a DNS issue. I added the appropriate switches and increased the softlimit from 2000000 to 4000000. See below: (basically a copy of LWQ) #!/bin/sh QMAILDUID=`id -u qmaild` NOFILESGID=`id -g qmaild` MAXSMTPD=`cat /var/qmail/control/concurrencyincoming` exec /usr/local/bin/softlimit -m 4000000 \ /usr/local/bin/tcpserver -v -H -R -l 0 -x /etc/tcp.smtp.cdb -c "$MAXSMTPD" \ -u "$QMAILDUID" -g "NOFILESGID" 0 smtp /var/qmail/bin/qmail-smtpd 2>&1 The timeouts stopped and now the response is about 20-25 sec some of the time and normal 1-2 sec. others. The server has a public and private network interface and is running Linux Masq (ie. 192.168. internal and a routable address external). If I attach a workstation on the public network it responds normally. It is the private network that is inconsistant. Web activity thru the Linux Masq is always normal. I even attached a single workstation to the inside to eliminate possible conflicts on the internal network. Same results. Everything seems to point to a DNS issue but the external network always seems normal. I hope I haven't overlooked the obvious but I probably have. Any guidance on where to look would be greatly appreciated. Thanks in advance, Bill __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!
