Enabling Sakai to both send and receive email requires setting a number of properties in
sakai.properties. In order to send mail Sakai requires the address (name or IP) of an external SMTP server that will accept mail from Sakai:
Sakai's SMTP server is Apache James for Sakai 10 and earlier and SubEthaSMTP from 11. Most sys admins prefer running a standard mailer like Postfix on port 25 and configuring it to forward requests to Sakai. You may also currently have a mailer service running on port 25 (Linux usually has it running by default). So consider setting Sakai's SMTP service to run on a different port (e.g., 8025) in order to avoid conflicts.
To enable Sakai to receive mail you'll need to set the following properties:
# flag to enable or disable SMTP service for incoming email (true | false)
# dns addresses used by SMTP service for incoming email. (only supported on versions <= Sakai 10)
# SMTP port on which incoming SMTP service listens.
# Recommend running on 8025, and using a standard mailer on 25 to forward mail to Sakai.
Additional settings can be enabled to add support emails for a variety of tasks.
# Email support address used in incoming email rejection messages.
# A variation on this that's used in some places instead of the one above! Best to set both of them
#To change the postmaster address in general
# Email address to send errors caught by the portal, and user bug reports in response.
# Email address used as the "from" address for any email sent by Worksite Setup tool or Site Info tool.
# Send an email to the user when the user is added.
#For msgcntr notifications
#Whether or not to send the real address as msgcntr notifications
