Notes / Tuning Information
  

  

   

Load balancing was provided by the Linux Virtual Server Project found at www.linuxvirtualserver.org
SMTP and POP connections were load-balanced using a least-connection scheduling algorithm
Direct routing was used to route the load balanced connections between servers
The kernel was patched with ipvs-1.0.1 patch

General Notes / Tuning Information





A Network Appliance F820 with 9 36GB drives in a single raid group
was used to store the mailboxes via NFS.
It was mounted with the NFS options: vers=3,tcp,noatime,wsize=32768,rsize=32768

Aphelion 2001 was used for the LDAP server.

Linux tuning paremeters:
echo 4096 >> /proc/sys/net/core/netdev_max_backlog
echo 2000000 >> /proc/sys/net/ipv4/tcp_max_tw_buckets
echo 0 >> /proc/sys/net/ipv4/tcp_window_scaling
echo 0 >> /proc/sys/net/ipv4/tcp_timestamps
echo 0 >> /proc/sys/net/ipv4/tcp_sack
echo 0 >> /proc/sys/net/ipv4/ip_forward

echo 1048576 >> /proc/sys/net/core/rmem_default
echo 1048576 >> /proc/sys/net/core/rmem_max

A 3Com 3300 switch (24 port 10/100Mb) was used for LAN connectivity.

Description of imsd options used:
-Vd  disable DNS lookup for clients
-L   name of an alternate debug log
-tpool minimum number of available processing threads (default = 16)
-tmax  maximum number of processing threads allowed (default = 16384)

Description of SMTPserver options used:
-Ca  host:service name of imsd administrative service
-rt  read timeout in seconds
-Cr  recipient number threshold causing queueing at low priority
-CD  enable automatic creation of mailbox directories
-na  Do not send AUTH
-I   name of the SMTP input queue (default is SMTP-in)
-D   limit delivery/relaying to allowed deliver/relay domains
-Sc  per client session threshold
-S   total session threshold
-ar  avoid reverse host address lookup
