The following installation is completed on the FreeBSD 5.2.1 system.

1. Update ports

# cvsup -gl 2 -h cvsup.freebsdchina.org / usr / share / example / cvsup / ports-suppile

2. Install the OpenSSL APACHE server

# CD / USR / PORTS / Security / OpenSSL

# make install

# make clean

# cd / usr / ports / www / apache2

# make install

# make clean

# vi /etc/rc.conf

Apache2_enable = "yes"

3. Install OpenWebmail

# CD / USR / PORTS / MAIL / OpenWebmail /

# make with_quota = yes install

# make clean

4. Install the postfix, answer questions with Yes during the installation process

# cd / usr / ports / mail / postfix /

# make install

# make clean

# vi /etc/rc.conf

In order to start Postfix to join:

Sendmail_enable = "yes"

Sendmail_flags = "- bd"

Sendmail_PIDFILE = "/ var / spool / postfix / pid / master.pid"

Sendmail_outbound_enable = "no"

Sendmail_submit_enable = "no"

5. Install VM-POP3D

# CD / USR / PORTS / MAIL / VM-POP3D

# make install

# make clean

6. Configure postfix

# vi /usr/local/etc/postfix/main.cf

Add to:

MyHostName = NERO.3322.org

Mydomain = NERO.3322.org

Virtual_Alias_maps = hash: / usr / local / etc / postfix / virtual

Alias_maps = hash: / usr / local / etc / postfix / aliases

DEFAULT_PRIVS = NoBody

Allow_mail_to_commands = alias, forward, include

ALLOW_MAIL_TO_FILES = Alias, Forward, Include

Below I join a virtual domain of Nero.3322.org and add a user LLZQQ

# vi / usr / local / etc / postfix / virtual

Add to:

Nero.3322.org Anything / / Use [TAB]

Llzqq@nero.3322.org

Llzqq.nero.3322.org / / [tab]

Execute the following command to generate virtual.db:

# CD / usr / local / etc / postfix /

# Postmap Virtual

# vi / usr / local / etc / postfix / aliases

Add to:

Llzqq.nero.3322.org:/var/spool/virtual/nero.3322.org/llzqq Execute the following command to generate aliases.db:

# cd / usr / local / etc / postfix

# Postalias Aliases

7. Configure VM-POP3D to turn it automatically

# cd /usr/local/etc/rc.d

# mv vm-pop3d.sh.sample VM-POP3D.SH

Configure OpenWebmail to support the Nero.3322.org domain, create the following files:

# vi /usr/local/www/cgi-bin/openwebmail/etc/sites.conf/nero.3322.org

=========================== Nero.3322.org ================================================================================================================================================================================================================ =====

Enable_AUTOREPLY NO

Enable_setForward No

Enable_vdomain YES

VDOMAIN_ADMLIST LLZQQ // Sets this domain administrator

VDOMAIN_MAXUSER 500

Quota_threshold 85

Delmail_ifquotahit no

Delfile_ifquotahit no

# mkdir -p /var/spool/virtual/nero.3322.org

# chown nobody /var/spool/virtual/nero.3322.org

# chgrp mail /var/spool/virtual/nero.3322.org# mkdir -p /usr/local/etc/virtual/nero.3322.org

# Touch /usr/local/etc/virtual/nero.3322.org/passwd

# chmod 644 /usr/local/etc/virtual/nero.3322.org/passwd

# htpasswd /usr/local/etc/virtual/nero.3322.org/passwd llzqq

# chmod 755 / usr / local / www / cgi-bin / openwebmail / etc / users

# sync

# reboot

8. Finally, log in to OpenWebmail via browser

4.0 Configuring POSFIX and adds some of the following in his profile

# vi /usr/local/etc/postfix/master.cf

--------------------- Master.cf ---------------------

SMTP-AMAVIS UNIX - - N - 2 SMTP

-o SMTP_DATA_DONE_TIMEOUT = 1200

-o disable_dns_lookups = yes

127.0.0.1:10025 INET N - N - - SMTPD

-o content_filter =

-o local_recipient_maps =

-o relay_recipient_maps =

-o SMTPD_RESTRICTION_CLASSES =

-o SMTPD_CLIENT_RESTRICTIONS =

-o SMTPD_HELO_RESTRICTIONS =

-o SMTPD_SENDER_RESTRICTIONS =

-o myneetworks = 127.0.0.0 / 8

--------------------- Master.cf ---------------------

# vi /usr/local/etc/postfix/main.cf

Content_filter = SMTP-AMAVIS: [127.0.0.1]: 10024

Ok, now a FreeBSD-based function is established, and the virtual domain administrator can log in to OpenWebmail to add, delete, etc., virtual users can modify their own passwords with OpenWebmail.
