Local Listener SMTP Service

The VersaLexCleo HarmonyCleo VLTraderCleo LexiCom application will process an incoming SMTP MIME message as follows:

  • If not a multipart message, the body of the message will be treated as a single file.
  • Each part of a multipart message will be treated as a single file.  Both inline and attachment disposition types are retained.
  • If present, a preamble before the first part of a multipart message will be logged and then discarded.  It will not be retained as a file.

Received multipart subtypes mixed, parallel, related, and nested multiparts will all be treated as simply one group of files.  Multipart/alternative requires special consideration since duplicate, alternative representations of the same information may be included.  Multipart/alternative will be processed as follows:

  • If any attachment disposition types are present, these parts are all retained as a group of files and the rest of the multipart/alternative parts are discarded.
  • Otherwise, if a text/plain content type is present, this part is retained as a single file and the rest of the multipart/alternative parts are discarded.
  • Otherwise, the message data is rejected by the VersaLexCleo HarmonyCleo VLTraderCleo LexiCom SMTP server.
