Questions tagged [rfc822]

RFC822 is the historical original standard for the format of email messages.

RFC5322 (which supersedes 2822, which in turn superseded the original 822) defines the basic format of email messages. Its companion document RFC5321 documents the SMTP transport protocol.

These days, you also need to know about and the various internationalization features which have been added to the email infrastructure over the years.

What is the difference between an `eml` file and an RFC822 email message?
