Hi,
I am using Linux with qmail-1.03 for the college's email service. We are
linked thru a VSAT connection to the ISP (ERNET-India). I use daemontools,
tcpserver and my installation is based on suggestions of Dave's lwq.html.
On average, about 5000 mails flow either way , but I find about 50%
deferrals , all of them with "Connected to [ IPaddress ] , but connection
died (#4.4.2)" , with or without a "Possible Duplicate !" tag.
Parameters are
paternalism:2
Silent concurrency limit : 250 ( changed and re-compiled . Also applied
dns patch).
concurrency set to 250 for both local and remote.
No percent hack, No QMQP
Queuelifetime : 2 days
timeoutconnect: 75 sec
timeoutsmtpd: 720 sec
timeoutremote: 720 sec
There is a local DNS server which caches requests.
Could the list guide me on how to fine tune qmail so that the
deferrals and denials can be reduced ?
Thanks in advace.
