port 587 for SMTP - Linux / Unix Administration

as far as i know, port 587 is used for SMTP as a workaround because many high speed ISP providers block port 25 to prevent spammers going thru their line. does anyone know if this is just a common practice, or if 587 is in some standard spec or recommendation? Xah org ∑ http://xahlee.org/...

    Is there a reason you couldn't do your own search at www.rfc-editor.org?
