E-mail howto

This document shows how to configure application server's e-mail service that is used by Simplicité to send e-mails.

Tomcat context-level configuration​

You can configure the dedicated mail/simplicite context service in the META-INF/context.xml, e.g.

<Resource
	name="mail/simplicite"
	type="javax.mail.Session"
	auth="Container"
	mail.from="..."
	mail.transport.protocol="smtp"
	mail.smtp.host="..."
	mail.smtp.port="..."
...
/>

As of version 3.1 this type of configuration is still possible but the bellow approach, by configuration, is more flexible.

Configuration-level configuration​

As of version 3.1 it is possible to configure the mail service properties as JSON in the MAIL_SERVICE system parameter.

For instance, to use a simple SMTP server you can set it like this:

{
	"mail.transport.protocol": "smtp",
	"mail.smtp.host": "<SMTP host>",
	"mail.smtp.port": "<SMTP port>",
	"mail.from": "<default sender email address>",
	"mail.debug": "<true|false>"
}

When mail.debug is set to "true", the output is quite verbose, it is not suitable for production.

The mail.from must be defined in 2 other parameters:

  • in EMAIL_DEFAULT_SENDER: default sender
  • and BPMALERT_FROM: used by Alert defined in a state transition

SMTP server with authentication​

If your SMTP server requires authentication you need to add these additional items:

{
	(...)
	"mail.smtp.auth": "true",
	"mail.smtp.user": "<your SMTP server username>",
	"password": "<your SMTP server password>"
}

GMail SMTP server​

To use GMail as SMTP server you need to configure an existing (and active) GMail account as follows:

  1. Log into your Google account (if you have multiple accounts, be sure that you are signed into the account you wish to send emails from).
  2. Open the following link and toggle the 'Allow less secure apps' option to ON. This is telling your Gmail server to allow it to be accessed by less secured apps.
  3. Set the MAIL_SERVICE with SSL or TLS protocol:

Using SSL protocol on port 465:

{
	"mail.from": "<default sender email address>",
	"mail.debug": "<true|false>",
	"mail.transport.protocol": "smtp",
	"mail.smtp.host": "smtp.gmail.com",
	"mail.smtp.port": "465",
	"mail.smtp.auth": "true",
	"mail.smtp.socketFactory.class": "javax.net.ssl.SSLSocketFactory",
	"mail.smtp.user": "<GMail account username>",
	"password": "<GMail account password>"
}

Using TLS protocol on port 587:

{
	"mail.from": "<default sender email address>",
	"mail.debug": "<true|false>",
	"mail.transport.protocol": "smtp",
	"mail.smtp.host": "smtp.gmail.com",
	"mail.smtp.port": "587",
	"mail.smtp.auth": "true",
	"mail.smtp.starttls.enable": "true",
	"mail.smtp.user": "<GMail account username>",
	"password": "<GMail account password>"
}

Sender email address​

You can override the sender email address configured above (mail.from) by setting the system parameter EMAIL_DEFAULT_SENDER (which can be overridden by the BPMALERT_FROM system parameter for the particular case of workflow alerts).

When this parameter is not set (or set to default), the mail.from is used.

Use an external service like Mailchimp, MailJet or Sendwithus​
