How to make sending emails via postfix fast?

Question

linux

There is a webserver, on it postfix. When sending a letter via PHP mail(), it takes about 15 minutes until the letter actually leaves. Tell me where to dig? The postfix config is:

queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
mail_owner = postfix
myhostname = extmail.DOMAIN.com
mydomain = DOMAIN2.ru
myorigin = $myhostname
inet_protocols = all
mydestination = $myhostname, localhost.$mydomain, localhost
unknown_local_recipient_reject_code = 550

mynetworks_style = subnet

mynetworks = 127.0.0.0/8,89.21.77.88/32

relay_domains = mysql:/etc/postfix/mysql-virtual_relay_domains.cf

smtpd_banner = $myhostname ESMTP $mail_name ($mail_version)

   ddd $daemon_directory/$process_name $process_id & sleep 5

An indiscreet question - have you tried reading the logs? :-) There after all all stages of passage of the letter on instances are reflected. Here you can see where it goes wrong.
