Adding an E-Mail Port

For this parameter...	Specify...
Package Name	The package associated with this port. When you enable the package, the server enables the port. When you disable the package, the server disables the port. If you replicate this package, Integration Server creates a port with this number and the same settings on the target server. If a port with this number already exists on the target server, its settings remain intact. This feature is useful if you create an application that expects input on a specific port. The application will continue to work after it is replicated to another server.
Alias	An alias for the port that is unique for this Integration Server. An alias must be between 1 and 255 characters in length and include one or more of the following: letters (a -z, A-Z), numbers (0-9), underscore (_), period (.), and hyphen (-).
Description	A description of the port.

For this parameter...	Specify...
Enable	Whether to enable (Yes) or disable (No) the e-mail port. The port can receive requests only when it is enabled.
Type	Type of mail server. Select POP3 or IMAP.
Host Name	Name of the machine on which the POP3 or IMAP server is running.
Port	Port on the e-mail server to which Integration Server is to connect. For a POP3 mail server, the defaults are 110 for explicit SSL and 995 for implicit SSL. For an IMAP mail server, the defaults are 143 for explicit SSL and 993 for implicit SSL.
User Name	User name that identifies you to the e-mail server.
Password	Password associated with the user name that identifies you to the e-mail server.
Transport Layer Security	Type of SSL encryption that Integration Server uses when communicating with an e-mail server. You can configure the port to use explicit, implicit, or no Transport Layer Security.
	Specify...	To...
	None	Default. Use a non-secure mode when communicating with an e-mail server. When you specify None, the e-mail server authenticates the e-mail client using only the username and password.
	Explicit	Use explicit security when communicating with an e-mail server. With explicit security, Integration Server establishes an un-encrypted connection to the e-mail server and then upgrades to the secure mode. With explicit Transport layer Security, Integration Server can communicate with e-mail servers that support and do not support SSL encryption. If the e-mail server does not support Transport Layer Security, Integration Server will disconnect the connection established to the e-mail server. You can then establish an un-secure connection with the e-mail server by selecting the None option in the Transport Layer Security field and enabling the port.
	Implicit	Use implicit security when communicating with an e-mail server. With implicit security, Integration Server always establishes an encrypted connection to the e-mail server. Only clients that support SSL will be permitted access.
Truststore Alias (optional)	Optional. Alias for the truststore that contains certificates presented by the e-mail server to Integration Server. If you do not select a truststore alias, the default truststore alias specified in the watt.security.trustStoreAlias property will be used. For more information about this property, see watt.security.. For more information about truststore alias, see Creating Keystore Aliases.
Time Interval	How often (in seconds) Integration Server is to check for e-mails in the POP3 or IMAP server.
Log out after each mail check	For use with IMAP and multithreading only. If you select Yes, Integration Server logs out a read-only thread to the IMAP mail server after checking for mail on that thread. The main read/write thread to the IMAP server remains intact. If you select No, all the read-only threads remain intact. Select Yes if your IMAP server restricts the number of connections it will allow to remain logged in.

For this parameter...	Specify...
Run services as user	If you select Yes in the Require authentication within message field, the Run services as user field remains blank because Integration Server expects the user name and password to be in the e-mail. If you select No in the Require authentication within message field, you must enter the user under which the service is to run on Integration Server.
Require authentication within message	If you select Yes, Integration Server checks for $user and $pass parameters in the Subject line of the e-mail. The user name is the user under which the service is to run on Integration Server. If you select No, you must specify the user in the Run services as user field above. When you select No, appears next to this field. Click to look up and select a user. The user can be an internal or external user.

For this parameter...

Specify...

Global Service (optional)

Service to be executed on Integration Server. This field overrides a service specified in the Subject line of the e-mail.

Default Service (optional)

Service to be executed if the e-mail does not provide a valid service in the Subject line and the Global Service field is blank.

Send reply e-mail with service output

Click Yes if you want Integration Server to send any output generated by the service to the original sender in an e-mail attachment. Click No if you do not want to do so. If the original e-mail contained multiple attachments, the reply contains an equal number of attachments.

Send reply e-mail on error

Click Yes if you want Integration Server to report any errors that occurred during service execution to the original sender in the Body portion of an e-mail. Click No if you do not want to do so.

Note:

For more information about sending e-mail notifications when errors occur, see Sending Messages About Critical Issues to E-mail Addresses.

Delete valid messages (IMAP only)

Click Yes if you want to delete a valid e-mail from the IMAP server once Integration Server has successfully received the e-mail. This setting helps prevent e-mails from accumulating on the IMAP server, possibly affecting disk space and performance. Integration Server always deletes e-mails on a POP3 server. Click No if you want to retain the e-mails on the IMAP server.

Delete invalid messages (IMAP only)

Click Yes if you want to delete invalid e-mails from the IMAP server. Click No if you do want to remove these e-mails from the server.

Invalid e-mails are those that reference services that cannot be invoked. For example, if the referenced service does not exist, the server will delete the e-mail. If the service was invoked, but encountered errors, the server considers the associated e-mail to be valid.

This setting helps prevent invalid e-mails from accumulating on the IMAP server, possibly affecting disk space and performance. Integration Server always deletes e-mails on a POP3 server.

Multithreaded processing (IMAP only)

Click Yes if you want Integration Server to use multiple threads for this port. This setting allows the port to handle multiple requests at once and avoid a bottleneck. Click No if you do not need this feature.

Number of threads if multithreading is turned on.

Tells Integration Server the number of threads to use for this port. The default is set to 0.

Note:

If the e-mail port is configured to allow multithreading and if the e-mail port receives a large number of messages in a short period of time, the e-mail port will monopolize the server thread pool for retrieving and processing messages. This will slow down the performance of Integration Server. To avoid this, you can limit the number of threads used to process messages received by the e-mail port by setting the watt.server.email.waitForServiceCompletion property. For more information about this property, see Server Configuration Parameters.

Invoke service for each part of multipart message

Specifies whether Integration Server invokes the service for each part of a multi-part message or just once for the entire message.

If you specify No, the entire e-mail is passed to the appropriate content handler and then to the specified service for execution. When you send an entire multi-part e-mail, make sure the server includes the e-mail headers from the beginning of the message, so that the content handler and/or service knows how to process the content type headers included in each part of the e-mail. See Include e-mail headers when passing message to content handler below.

If you specify Yes, Integration Server treats each part of the message individually. That is, Integration Server sends each part to the content handler and then to the specified service. When you specify Yes, you probably do not want to include the e-mail headers from the beginning of the message, because each section has its own headers that the content handler and/or the service already knows how to process. See Include e-mail headers when passing message to content handler below.

Include e-mail headers when passing message to content handler

Specifies whether Integration Server includes the e-mail headers when passing an e-mail message to the content handler. The e-mail headers are typically found at the beginning of an e-mail message. Specify Yes if you are processing a multi-part message as a single message. This ensures that the content handler and/or service can properly process the body of the e-mail. Specify No if you are processing the different parts of an e-mail individually. If you are processing a single-part e-mail, you probably do not want to include e-mail headers.

E-mail body contains URL encoded input parameters

Specifies how Integration Server treats input parameters it finds in e-mail messages. With this value set to Yes, Integration Server considers a string such as ?one=1+two=2 to be a URL encoded input parameter. It then decodes this string into an IData object, puts it into the pipeline, and passes it to the service. With this value set to No, Integration Server treats the string as plain text and passes it to the appropriate content handler.

Note:

If you set port access restrictions, be sure the watt.net.email.validateHost server configuration property is set to true, so Integration Server honors your IP access restrictions.
