NAME

auth_vpopmail_sql - Authenticate to vpopmail via MySQL

DESCRIPTION

This plugin authenticates vpopmail users directly against a standard vpopmail MySQL database. It makes the not-unreasonable assumption that both pw_name and pw_domain are lowercase only (qmail doesn't actually care). If you are using CRAM-MD5, it also requires that vpopmail be built with the recommended '--enable-clear-passwd=y' option, because there is no way to compare the crypted password.

CONFIGURATION

 echo "dbi:mysql:dbname=vpopmail;host=127.0.0.1" > config/vpopmail_mysql_dsn
 echo "vpopmailuser" > config/vpopmail_mysql_user
 echo "vpoppasswd" > config/vpopmail_mysql_pass

This can be a read-only database user since the plugin does not update the last accessed time (yet, see below).

This module supports PLAIN, LOGIN, and CRAM-MD5 authentication methods. You can disable undesired methods by editing this module and uncommenting the lines in the register() sub. See the POD for Qspmtpd::Auth for more details on the ramifications of supporting various authentication methods.

The remote user must login with a fully qualified e-mail address (i.e. both account name and domain), even if they don't normally need to. This is because the vpopmail table has a unique index on pw_name/pw_domain, and this module requires that only a single record be returned from the database.

LIMITATIONS

This authentication modules does not recognize domain aliases. So, if you have the domain example.com, with domain aliases for example.org and example.net, smtp-auth will only work for $user@example.com. If you have domain aliases, consider using another plugin (see SEE ALSO).

FUTURE DIRECTION

The default MySQL configuration for vpopmail includes a table to log access, lastauth, which could conceivably be updated upon sucessful authentication. The addition of this feature is left as an exercise for someone who cares. ;)
