Dynamic e-mails are created with variable content and SMTP parameters. For instance, the list of recipients may be generated from a database query. For the dynamic content of an e-mail body, you may also use the output from other actions (like system messages, error messages, etc.), text data from a file, or any other backend system.
Example File (Builder project Add-ons/EMail):
 | <your example path>\Add-ons\EMail\uml\smtpEmailing.xml |
Dynamic E-mail Activity Diagram
The input parameters will be mapped to objects that will be passed to the SMTP adapter in the activity diagram (see picture below).
Figure: Dynamic E-mail Activity Diagram
In the action node create parameters parameters, the input parameters of input object email are mapped to the central buffer nodes (dynamic parameters) that will in turn be passed to the SMTP adapter (action node mail the content).
Header Parameters
The xUML Runtime assigns a correlation ID to each adapter call. This ID is stored in header field X-Bridge-CorrelationID. Adapter calls can be identified by this ID. Also, it is logged to the transaction log.
SMTP Adapter Parameters
Supplies the e-mail address of the sender of the e-mail. It contains the plain address without comments or real name parts (e.g. order@e2e.ch). If you do not specify a sender, the e-mail cannot be delivered successfully. The sender defines the Return-Path value of the message header. Some smart hosts check, if the sender's address is legitimate before accepting the e-mail. If the from field is provided in the header parameters, its value will be displayed in the e-mail client instead of the sender. Supplies an array of custom SMTP header parameters with name - value pairs (to, cc, bcc, from, subject, reply-to, etc.). If you use the e-mail client function Reply All upon receiving the e-mail, the recipients of the new e-mail will be generated from the original SMTP header parameters, and the sender, unless the from field was defined in the message header. Examples:Name Type Direction Description domainName String in Supplies the sender domain the e-mail is sent from. Normally this is the FQDN (Fully Qualified Domain Name) of the system the Bridge is running on (e.g. e2e.ch). server String in Supplies the name of the smart host. If no server is specified, localhost will be used. port Integer in Supplies the SMTP port of the smart host. If no port number is specified, 25 will be used. user String in Supplies the user part of the credentials. password String in Supplies the password part of the credentials. sender String in recipients Array of String in Each array element identifies one recipient of the e-mail, and contains the plain address without comments or real name parts. headerParameters Array of MIMEHeaderField in
Value: Customers
Value: Order E2E Bridge
Value: info@e2e.chcontent Blob in The body of the e-mail may contain any kind of data and is wrapped in an object of base type Blob.
Testing Dynamic E-mail
The following figure shows input parameters entered in the SOAP Test Tool for the dynamic e-mail example shown in figure Dynamic E-mail Activity Diagram above.
Figure: Input Parameters for a Dynamic E-mail
The picture below shows the received e-mail displayed in an e-mail client.
Figure: Example of a Received E-mail
The address "test receiver" in the to field of the e-mail client is not an e-mail address of one of the real recipients. The real recipients are test2@e2e.ch and test3@e2e.ch as defined in the recipients array of the input object sent to the service (see Figure: Input Parameters for a Dynamic E-mail).
The same with the sender address "test sender", the real e-mail address is test1@e2e.ch and is set as return-path in the message header. The message header of this e-mail is shown below:
