Hi Jean, The place to look for internet protocols is the RFC's http://www.cis.ohio-state.edu/hypertext/information/rfc.html Standard for the format of ARPA internet text messages. http://www.cis.ohio-state.edu/htbin/rfc/rfc0822.html Mime messages part1 http://www.cis.ohio-state.edu/htbin/rfc/rfc2045.html Updates and extension proposals are always being added so use the search engine to find the most current version of the protocol you are after. http://www.cis.ohio-state.edu/Excite/AT-rfcsquery.html Cheers, Allen K ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, June 28, 2000 11:55 PM Subject: [REBOL] Email standard definition ? > Hi, > > does anyone know, where I can find the definition of the standard(s) used > for email ?
