The recent modification (1.625) have finally enabled one of my system to
deliver huge amounts of email without a problem.
Hardware:
NexGen 586-100 48M Ram 10G HD (Mixed SCSI+IDE), 3 Ethernet Boards
Software:
Debian 1.3, Linux 2.0.29, Exim 1.625 (.deb available from
ftp.fuller.edu/Linux)
Running exim is one of the minor functions of this machine. Main functions
are
1. Full UseNet Feed
2. FTP Site and Mirror Site for the Debian Project
3. External DNS Server
4. Router/NAT for our Library
Delivery of exim is restricted to only take place when the load is <2.0
Notable entries in /etc/exim.conf
split_spool_directory = true
freeze_tell_mailmaster = true
ignore_errmsg_errors = true
deliver_load_max = 10
deliver_queue_load_max = 99
queue_only_load = 2
smtp_accept_queue = 10
queue_run_max = 5
message_size_limit = 300000
return_size_limit = 10000
I needed to set deliver_queue_load_max very high in order to insure that
the mail queue is completely scanned. Otherwise exim will abort in the
midst of a queue run when the load gets higher than 2.0 and some messages
will never be processed.
I hope to be able to test the machine with a load of up to 200.000 in the
next days.
