How incoming and outgoing email works
Jive communities can both send emails to user and receive emails from users.
When sending email, Jive uses a multi-part format, where the email contains both a plain text version of the message and an HTML version. If user's email client supports HTML rendering, then the user most likely sees the HTML-formatted version. If a user is using an older email client or an email client on a mobile device with limited rendering capabilities, the user may see only the plain text version of the email.
When receiving and processing incoming emails, Jive only consumes the plain text portion of the multi-part email.
