hi everyone,
I have been working on putting postfix email server on unbuntu 8.04
server and after a very steep learn curve think I am ready to go online.
But I don't know if it is secure so below is what i have done. I need to
know if I have missed anything. So does anyone have anything I really
need to look out for.
I have created a virtual email server with the following programs
ubuntu server, dovecot, mysql backend,Postfix <http://www.postfix.org/>,
Apache, <http://www.apache.org/> PHP, <http://www.php.net/>
Postfixadmin, <http://high5.net/postfixadmin/> Squirrelmail,
<http://www.squirrelmail.org/> Amavisd-new,
<http://www.ijs.si/software/amavisd/> Spamassassin.
<http://spamassassin.apache.org/>
my main.cf looks like this,
myhostname = mta
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = mta.rbc.com, mta, localhost.localdomain, localhost
relayhost =
mynetworks = 127.0.0.0/8, 192.168.1.2/24
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all
# Virtual Mailbox Domain Settings
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
virtual_mailbox_limit = 51200000
virtual_minimum_uid = 5000
virtual_uid_maps = static:5000
virtual_gid_maps = static:5000
virtual_mailbox_base = /home/vmail
virtual_transport = dovecot
# Additional for quota support
virtual_create_maildirsize = yes
virtual_mailbox_extended = yes
virtual_mailbox_limit_maps =
mysql:/etc/postfix/mysql_virtual_mailbox_limit_maps.cf
virtual_mailbox_limit_override = yes
virtual_maildir_limit_message = Sorry, the your maildir has overdrawn
your diskspace quota, please free up some of spaces of your mailbox try
again.
virtual_overquota_bounce = yes
dovecot_destination_recipient_limit = 1
content_filter = smtp-amavis:[127.0.0.1]:10024
