Hi I am configuring the Appian Mail Server to recieve email from an E

Aayush- here is some additional information on the way the password.propeties file is managed:

Hi Alex
I forgot to mention that I am using Appian 7.2

When the app server starts up, configurations in password.properties are consumed and the file is deleted. This is expected behavior.

Hi Alex,
Thanks for the clarification, but still I am not able to start the process by email.
Please find the whole configuration below:
custom.properties
conf.data.primary.datasource=jdbc/MyAppian72DB
conf.data.datasources=jdbc/myappian72RDB
conf.mailhandler.mail.smtp.host=<ipaddress>
conf.mailhandler.mail.smtp.auth=false
conf.suite.ANONYMOUS_ACCESS=true
resources.appian.process.email-expressions.email.prefix.process=Support
resources.appian.process.email-expressions.email.prefix.processmodel=Support
resources.appian.process.email-expressions.email.domain=<domain>
conf.mailhandler.email.domain=<domain>
conf.jms.jmsInstalled=true
server.conf.exec.AUTOARCHIVE_DELAY=25
conf.suite.SERVER_AND_PORT=<ipaddress of server>:<port>
conf.content.download.inline=true
conf.mailhandler.alias.<username>=processmodeluuid<uuid>

Now as Alias is set so the ejb-jar.xml is edit to input the details:
<activation-config>
<activation-config-property>
<activation-config-property-name>ejbName</activation-config-property-name>
<activation-config-property-value>EmailHandlerBean</activation-config-property-value>
</activation-config-property>
<activation-config-property>
<activation-config-property-name>mailServer</activation-config-property-name>
<activation-config-property-value>mailserver</activation-config-property-value>
</activation-config-property>
<activation-config-property>
<activation-config-property-name>mailFolder</activation-config-property-name>
<activation-config-property-value>INBOX</activation-config-property-value>
</activation-config-property>
<activation-config-property>
<activation-config-property-name>storeProtocol</activation-config-property-name>
<activation-config-property-value>IMAPS</activation-config-property-value>
</activation-config-property>
<activation-config-property>
<activation-config-property-name>starttls</activation-config-property-name>
<activation-config-property-value>true</activation-config-property-value>
</activation-config-property>
<activation-config-property>
<activation-config-property-name>userName</activation-config-property-name>
<activation-config-property-value>username</activation-config-property-value>
</activation-config-property>
<activation-config-property>
<!-- polling interval in milliseconds
the setting provided below is every 5 minutes
consult your mail admin for acceptable frequecy -->
<activation-config-property-name>pollingInterval</activation-config-property-name>
<activation-config-property-value>300000</activation-config-property-value>
</activation-config-property>
</activation-config>

Accordingly changes are done in password.properties for setting the password.

Please let me know if I have done any mistake in the configuration mentioned above.
Or if any other configurations are required.

Have you enables public events?
forum.appian.com/.../General_Tab

Yes, Public Event is enabled.
Also, Start event is triggerd by Recieve Message (Email) with no event conditions.
Process model is published.
Subject of the mail sent to configured email id = [DestinationPMUUID=<uuid>]

To clarify, you are able to start this process by email without any conditions set. Once you set conditions it no longer works?

Sorry Alex, I am not able to start the process even without any conditions set.

Hi aayusha, could you please let me know if you were abot to figure it out?

I am not sure, what went wrong that time.
But here is what needs to be done.
Set following in custom.properties.
conf.suite.ANONYMOUS_ACCESS=true;
conf.mailhandler.mail.smtp.host=<domain>
conf.mailhandler.mail.smtp.auth=true / false; #(on setting it to true, one needs to edit the password.properties too)
conf.mailhandler.mail.user=username #(this is required only if above property is set to true.)
Edit ejb-jar.xml
and edit ejbName, mailServer,folder,storeprotocal,startls, username (has to be same as we had in custom.properties)
In password.properties
set the conf.password.EmailHandlerBean.EMAIL_HANDLER=<password>
Process model - public event is set to true with a revcieve email message on start node. PM is published and not in My Models.
