Construct a virtual domain email server unrelated to the System user

Article Title: Construct a virtual domain email server unrelated to the System user. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
Operating System: FreeBSD 4-stable
　　
Update ports
　　
Cvsup-gL 2-h cvsup.freebsdchina.org/usr/share/examples/cvsup/ports-supfile
　　
Install the apache server
　　
Cd/usr/ports/www/apache2/
Make install clean
　　
Install openwebmail. Add WITH_QUOTA to prepare for the disk quota in the future.
　　
Cd/usr/ports/mail/openwebmail/
Make WITH_QUOTA = yes install clean
　　
Install postfix, and answer all questions during the process y
　　
Cd/usr/ports/mail/postfix/
Make install clean
　　
Modify:
/Etc/rc. conf
　　
Join:
　　
Sendmail_enable = "YES"
Sendmail_flags = "-bd"
Sendmail_pidfile = "/var/spool/postfix/pid/master. pid"
Sendmail_outbound_enable = "NO"
Sendmail_submit_enable = "NO"
　　
This was prompted during the make install operation, but I forgot to configure it once, but the system still works normally and I still don't fully understand what the problem will be.
　　
Install vm-pop3d
　　
Cd/usr/ports/mail/vm-pop3d/
Make install clean
　　
Configure postfix
　　
Modify:
/Usr/local/etc/postfix/main. cf
Join
　　
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
　　
The last two are very important, because the include feature in aliases is disabled by default, and this feature is used when openwebmail modifies the aliases file.
　　
Modify:
/Usr/local/etc/postfix/virtual
Join:
　　
Jayvan.com # At least add a tab. Otherwise, an error occurs.
Jayvan@jayvan.com jayvan.jayvan.com
　　
In the above example, I add a virtual domain of jayvan.com and add the first user jayvan as the system administrator.
　　
Run:
　　
Cd/usr/local/etc/postfix/; postmap virtual
　　
Generate virtual. db
　　
Modify:
/Usr/local/etc/postfix/aliases
　　
Join
　　
Jayvan.jayvan.com:/var/spool/virtual/jayvan.com/jayvan
　　
Run:
Cd/usr/local/etc/postfix/; postalias aliases
　　
Generate aliases. db
　　
Configure Automatic vm-pop3d execution
Modify:
/Etc/inetd. conf
　　
Join:
　　
Pop3 stream tcp nowait root/usr/local/sbin/vm-pop3d vm-pop3d-u nobody
　　
　　
Modify:
/Etc/rc. conf
　　
Join:
Inetd_enable = "YES"
　　
Of course, you can also use the rc. d script for execution.
　　
Configure openwebmail to support the jayvan.com domain
Add file:
/Usr/local/www/cgi-bin/openwebmail/etc/site. conf/jayvan.com
　　
The file must be a virtual domain name.
File Content:
　　
Auth_module auth_vdomain.pl
Auth_withdomain yes
Mailspooldir/var/spool/virtual/jayvan.com # note that the directory name and domain name are consistent
Use_syshomedir no
Use_homedirspools no
Enable_autoreply no
Enable_setforward no
Enable_vdomain yes
Vdomain_admlist jayvan
Vdomain_maxuser 100
Vdomain_vmpop3_pwdpath/usr/local/etc/virtual # This is the vm-pop3d default directory for passwd
Vdomain_vmpop3_pwdname passwd
Vdomain_vmpop3_mailpath/var/spool/virtual
Vdomain_postfix_aliases/usr/local/etc/postfix/aliases
Vdomain_postfix_virtual/usr/local/etc/postfix/virtual
Vdomain_postfix_postalias/usr/local/sbin/postalias
Vdomain_postfix_postmap/usr/local/sbin/postmap
　　
Run:
　　
Mkdir-p/var/spool/virtual/jayvan.com
Chown nobody/var/spool/virtual/jayvan.com
Chgrp mail/var/spool/virtual/jayvan.com
　　
Mkdir-p/usr/local/etc/virtual/jayvan.com
Touch/usr/local/etc/virtual/jayvan.com/passwd
Chmod 644/usr/local/etc/virtual/jayvan.com/passwd
　　
Htpasswd/usr/local/etc/virtual/jayvan.com/passwd jayvan
　　
Chmod 755/usr/local/www/cgi-bin/openwebmail/etc/users # this is very important. By default, this directory permission will cause openwebmail to be inaccessible.
　　
Restart the system to start postfix and vm-pop3, and then you can use it.
You can add an email account after logging on to openwebmail with the system administrator account. Note that you must use the complete email address as an account when logging on, for example:
Jayvan@jayvan.com
　　
How to make quota take effect has not been studied yet. I think this combination is good for the internal email servers of dozens of small companies. The Network Disk function of openwebmail saves the trouble of setting up personal file server sharing.
Currently, it does not seem that openwebmail can automatically set a group account. If it does not exist, this is a disadvantage. Although the automatic account registration function is very useful, it is not too great for company users of this type. Users added to openwebmail can barely meet the requirements.
