B. Write a matcher for the set of messages we want to delay, route them
to a custom processor. In that processor have a custom Mailet which
writes to a custom Spool repository and runs a number of threads which
then pluck from that repository using an accept(delay) call.
  


You want to use Plan B, and you want to base it off of the current
branch_2_1_fcs code, in which we made some changes related to the spool
interface.  Write a custom mailet based upon RemoteDelivery that holds
messages in its queue until ready to deliver, then posts them back to 
the
pipeline.

Was headed down the RemoteDelivery Plan B path, but I am getting these 
in the logs and my custom spool is not getting created.
Would going to branch_2_1_fcs fix this? Or am I just missing something 
in the config or setup? Code snippet for creation is below as well.

    String spoolPath = getInitParameter("spool");
    if (spoolPath == null) {
       spoolPath = "file:///../var/mail/guidspool";
    }
    ComponentManager compMgr = 
(ComponentManager)getMailetContext().getAttribute(Constants.AVALON_COMPONENT_MANAGER); 

    try {
       // Instantiate a MailRepository for spooled mails
       MailStore mailstore = (MailStore) 
compMgr.lookup("org.apache.james.services.MailStore");
              DefaultConfiguration spoolConf
          = new DefaultConfiguration("repository", 
"generated:MsgGuidMailet.java");
       spoolConf.setAttribute("destinationURL", spoolPath);
       spoolConf.setAttribute("type", "SPOOL");
       this.spool = (SpoolRepository) mailstore.select(spoolConf);
    } catch (ComponentException cnfe) {
       log("Failed to retrieve Store component:" + cnfe.getMessage());
    } catch (Exception e) {
       log("Failed to retrieve Store component:" + e.getMessage());
    }

My bad yet again. Ouch. Was not picking up the new config.xml when 
deploying my modified james.sar, and the default path of 
"file:///../var/mail/guidspool" was unresolveable.

Thanks again!
