Qpsmtpd:auth/auth imap
NAME auth_imap - Authenticate to an IMAP server
DESCRIPTION This plugin authenticates against any IMAP server you wish (it also supports SSL). You need to specify the IMAP server and port number in the plugins configuration file like so:
auth/auth_imap 192.168.0.1 143
Without any options, it defaults to connecting to the IMAP server on localhost on port 143.
This plugin requires the Net::IMAP::Simple::SSL CPAN module. Options from that module can be added to the $server->() constructor below if your IMAP server requires older versions of SSL rather than TLS or for connection debugging ( debug => 1, ssl_version => "SSLv3", etc.). While you can adjust these settings, the plugin should work as is for a typical IMAP server.
See the Net::IMAP::Simple POD for details on how tune the constructor parameters.
Note that auth_imap requires that you use AUTH PLAIN or AUTH LOGIN mechanisms which means that communication between your e-mail client and Qpsmtpd - and between Qpsmtpd and your IMAP server - should be encrypted. There are several approaches to enabling encrypted password storage on the IMAP server. For dovecot2 see: http://wiki2.dovecot.org/HowTo/CRAM-MD5
This plugin is suited for authorizing user connections to a Qpsmtp SMTP server acting as a relay or a primary mail server. The principal benefit is ease of adminstration when an existing IMAP service is already established.
