How to configure Appian to receive emails?

Aneesh, please see the documentation for detailed instructions on how to receive email: forum.appian.com/.../Mail_Server_Setup

Alex. Thanks.. But we are using Appian 6.6.1 and for 6.6.1 it says the password should also be in the ejb-jar.xml file and not in a separate file?

Is that correct for Appian 6.6.1?

Also after performing all 4 steps:-

1) Configure receive emails using ejb-jar.xml
2) Changing conf.suite.ANONYMOUS_ACCESS = true in custom.properties
3) Creating alias using conf.mailhandler.alias in custom.properties
4) Enabling Public Events on Process Models

Do we need to also specify any condition in the Receive Message Setup i.e. --> Event Conditions --> Start process only if conditions are true?

Or we can leave this part blank and the Process Model will auto-receive all emails after the above setup?

Setting up the alias is optional. If it is another system sending emails and not users, I would make sure that emails contain information for Appian to parse and kick off processes. You do not have to setup conditions in the events but in process model properties you need to setup check the "Public Events" checkbox to allow the guest user to kick it off.
