How to implement a script that listens for new mail and then perform an action

I have an apache James mail server setup and I would like to create a script that will listen for new mail and then communicate with an Asterisk server to call a user phone number and read the message. I assume this is possible but cannot find any information. I have been using perl scripting for other tasks so if I could do this with p开发者_运维知识库erl that would be great.

Thanks in advance

A solution would be to set up a cron job to run a perl script that uses something like Mail::POP3Client to check for new messages and sends something to Asterisk using (maybe) Asterisk::AGI. If the CPAN modules don't do what you need, you can always have the perl script execute system calls to interface with command-line tools that are capable of checking POP or interfacing with Asterisk.

I guess the best way to do that is to write a Mailet in java and put it in configuration to make it listen for the all mails in the root processor.

For Apache James 3.0-beta5 steps would be something like this:

1. Write the Mailet i.e:

   import org.apache.mailet.*;
   public class myMailet extends GenericMailet {
     private String aParameter;
     @Override
     public void init(MailetConfig cfg) throws MessagingException {
       super.init(cfg);
       aParameter = getInitParameter("myNeatParameter"); // use this if you need to use some parameters specified inside the mailetcontainer.xml
     }
   
     @Override
     public void service(Mail email) throws MessagingException {
       doYourThingWith(email);
     }
   
     private void doYourThingWith(Mail email){
       // TODO something with the email
     }
   }
   

2. Build the Mailet into a jar file

3. Add the resulting jar file to /conf/lib folder

4. Edit /conf/mailetcontainer.xml file where you would add this:

   <mailet match="All" class="myMailet">
       <myNeatParameter>some value</myNeatParameter>
   </mailet>
   

   as a child element to the root processor (or whatever you think is proper).

5. Restart James

Well it's not a script, but it is very good (if not even the best) solution.

You could use Mail::POP3Client to poll the mailbox for messages. Or if the mailbox supports IMAP and you want to continuously monitor it, use an IMAP module, perhaps Net::IMAP::Simple ?

I just googled for [Asterisk Perl] and a guide called "How to Write a Perl AGI Application" appeared on the first page. It describes how to use the Asterisk::AGI module to connect to an Asterisk server using Perl.

Finally, you'll need a text-to-speech application. I'm sure there are many of these available. They probably won't be written in Perl, but there may be existing Perl interfaces for them.
