For OpenACS to process incoming Emails you need to follow these steps:

Furthermore take a look at this OpenACS Forums message. 

Assumptions: 

 

hostname: mail.service0.com (note, it is mandatory that the hostname is the hostname of the server and does not equal an MX record).

oacs user: service0

linux user: service0

home dir: /home/service0

users mail dir: /home/service0/mail

website: www.service0.com

myhostname=mail.service0.com
myorigin=$myhostname
inet_interfaces=$myhostname, localhost
mynetworks_style=host
virtual_alias_domains = www.service0.com
virtual_maps=hash:/etc/postfix/virtual
home_mailbox=mail/

1. Install postfix (e.g. by getting RPM for RHEL4
   • Install smtp (for postfix)
   • Install metamail (for acs-mail-lite)
   • Edit /etc/postfix/main.cf 
   • Edit /etc/postfix/virtual and add the regular expressions to catchall incoming emails. 
     

     @www.service0.com service0 

     This is required for notifications and acs-mail-lite to 
     
     work. You need to add more lines for other packages that 
     
     also process emails.

   • Edit /etc/postfix/master.cf - uncomment this line so that postfix is able to process incoming emails
     

     smtp inet n - n - - smtpd

   • Create a mail directory as service0
     

     mkdir /home/service0/mail

   • Configure Notifications Parameters 
     

     EmailDomain: www.service0.com 
     
     EmailQmailQueue: /home/service0/mail 
     
     EmailReplyAddressPrefix: notification 
     
     EmailQmailQueueScanP: 1

   • Configure Mail Services Lite Parameters 
     

     BounceDomain: www.service0.com 
     
     BounceMailDir: /home/service0/mail 
     
     EnvelopePrefix: bounce 
     
      

   • Configure other packages likewise
   • Call postmap to recompile virtual db: 
     

     postmap /etc/postfix/virtual

   • Restart Postfix 
     

     /etc/init.d/postfix restart

   • Restart OpenACS 
     
     Note: if both acs-mail-lite and notifications 
     
     are checking for incoming mails the rule "First comes first serves" applies. In future only acs-mail-lite should sweep and delete processed messages.
   • if you send a test mail to notification-191931-2960@mail.cognovis.de notifications should recognize it and handle it.

A sweeper procedure like acs-mail-lite::load_mails should scan the e-mails which are in the Maildir directory on a regular basis and process them (using a parsing procedure). Then it should fire off callbacks. But before it parses the e-mails, it should check if the e-mail came from an auto mailer. Vinod has done this using procmail as follows below, maybe we could get this dragged into TCL code (using regexp or a procmail recipe parser) instead, removing the need for setting up procmail in the first place. 

Revised procmail filters:
