Install vpopmail (Source)
Note : Vpopmail is currently under active development. At the time of this writing, version 5.4.13 is the latest. There is no RPM at this time, however, I may create one soon.
Vpopmail must be configured, compiled, and installed as root.
First we create the user and group for vpopmail.
rootshell> groupadd -g 89 vchkpw
rootshell> useradd -u 89 -g vchkpw vpopmail
rootshell> tar zxvf /path/to/vpopmail-5.4.13.tar.gz
rootshell> cd vpopmail-5.4.13
rootshell> ./configure --enable-logging=v --enable-clear-passwd --enable-auth-module=mysql --enable-auth-logging --enable-sql-logging --disable-passwd --enable-valias --disable-mysql-limits
The configuration options above are defined as follows :
--enable-logging=OPT
Log to syslog: n=nothing, e=errors only (default), y=all attempts, p=errors with passwords, v=verbose (all attempts, with passwords).
--enable-clear-passwd
Store a cleartext version of the password in addition to the encrypted version.
--enable-auth-module=MOD
Nominate how to store the vpopmail account information (cdb (default), mysql, pgsql, ldap, oracle, sybase, or activedir).
--enable-auth-logging
Record time and ip of last auth attempt. Valid only for CDB, MySQL, PGSQL, LDAP, ActiveDir.
--enable-sql-logging
Enable authentication logging to MySQL/Postgres.
--disable-passwd
Disable /etc/passwd (or shadow) accounts in addition to virtual domains.
--enable-valias
Store email aliases in MySQL.
--disable-mysql-limits
Don't use MySQL to store limits instead of .qmailadmin-limits files.
rootshell> make
rootshell> make install-strip
Vpopmail installation is now complete. There is still a bit of configuration to be done. See the below configuration section for more information.
