Mail Interchange

With the increased use of the Internet and the ease of communicating with people around the world, an email message can be viewed on many platforms and dozens of locales. Standards for email interchange, however, are restricted by desktop machines for which the default email standard is Simple Mail Transfer Protocol (SMTP), which supports only 7-bit transmission channels.

The sending agent converts the body of the message into a standard format and labels it as body. The receiving agent looks at the body and, if it supports the character encoding, converts the body into the local character set.

Because dtmail now uses the Language Conversion Library (LCL), dtmail has the capacity to support multibyte characters in both the subject line, the mail body, and in attachments. dtmail also has the ability to use characters of different encodings within the same mail, for example, SJIS and EUC encodings for the Japanese (ja) locale.
