E-mail Server Administration

This section provides information for administrators regarding E-mail Server. In addition to the topics on this page, there is also information on the following:

• How E-mail Server uses JavaMail properties.
• The types of notification of delivery status and message disposition.
• How to customize the e-mails from external resources.

See also the directions on enabling both UCS and E-mail Server to run as Windows Service when TLS is configured.

Limitations

• Attachments—There is no limit on the size of attachments to e-mails. You can use the maximum-msg-size option to limit the overall size of incoming messages (that is, the total size of all message parts, including the body and any attachments).
• UCS:
  • E-mail Server 8.1.2 can work only with UCS 8.1.1 or later (however UCS 8.1.1 can work with any version of E-mail Server).
  • E-mail Server 8.1.3 or later can work only with UCS 8.1.3 or later.

List of Attached Files

Starting in release 8.1.0, inbound e-mails can include an attached data type _AttachmentFileNames, which contains a list of the names of files attached to the inbound e-mail.

Handling Unparsable E-Mails

If E-mail Server is unable to parse an incoming e-mail, it creates a new e-mail interaction (a "wrapping message") with the following characteristics:

• The header is the same as the header of the original, unparsable e-mail.
  • If the header of the original e-mail is unparsable, the subject of the new interaction is Unknown subject.
  • If the From address of the original e-mail is not valid, the From address of the new interaction is unknown@<default_domain>, where <default_domain> is the domain specified by the default_domain configuration option of the E-mail Server application.
• The text of the new interaction is Error encountered during preprocessing of this message + <reason_for_failure> + Original Incoming Email is attached to this Email.
• The original e-mail is attached to the new e-mail.
• The new e-mail has an attached key-value pair, whose key is _WrappingMessageReason and whose value is a text string that describes the reason for creating the wrapping message.
