With the advent of newer message formats that allow richer text, it is possible for an encoded line of text to wrap to a new line at the end of a sentence, thereby causing the period to be placed on a line by itself. This behavior occurs most often in the Hypertext Markup Language (HTML) message format.
SMTP SpecificationsIn Section 4.5.2 of the RFC 821, entitled Transparency, the specification requires the client to place a second period on lines that occur with a single period where additional text is present. When the receiving SMTP server encounters the double period in such cases, it removes the additional period and continues processing the message body.
