Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Currently I'm getting a speed of 5 emails /sec from Interspire to postfix server. I tuned each and every parameter to the max level, even then didn't get any increase in speed.

Here I'm pasting my config

Postconf -n

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
debug_peer_level = 2
default_process_limit = 1000
header_checks = regexp:/etc/postfix/header_checks.regex
html_directory = no
inet_interfaces = ****************
inet_protocols = ipv4
mail_owner = postfix
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain, localhost
mynetworks = **********, 127.0.0.0/8, ***********
newaliases_path = /usr/bin/newaliases.postfix
qmgr_message_active_limit = 100000
qmgr_message_recipient_limit = 100000
queue_directory = /var/spool/postfix
sample_directory = /usr/share/doc/postfix-2.6.6/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
smtpd_client_connection_count_limit = 0
smtpd_client_connection_rate_limit = 0
smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination
smtpd_sasl_auth_enable = yes
smtpd_sasl_path = /var/spool/postfix/private/auth
smtpd_sasl_type = dovecot
unknown_local_recipient_reject_code = 550

Interspire Support told me that the error could be in postfix configuration. Is there any way to increase rate of accepting messages in postfix. Please give suggestions.

It's kind of hard to tell from that output, but nothing stands out at present. Can you format it a bit cleaner? The speed will be limited by hardware of course, as well as any policy checks(such as running mail through Amavisd or post-grey), re-writes, etc.
