It pre-pends 'http://' and makes the link clickable (i.e. wraps it in ). As a default that makes sense for things beginning www. - but not for everything beginning ftp. In my case, I was using the plugin WP Better Emails, and sent out an email with this line (approx): `Here is the FTP server: ftp.example.com` WP, by default, ""helpfully"" totally mangles this into: `Here is the FTP server: http://ftp.example.com` The recipient of my email now believes that I was sending him an HTTP link, and is confused that it does not work. But in fact I never sent such a link - that was WordPress mangling what I did send. Sure, some FTP servers will also have HTTP listening. But by default WordPress assumes that they all do, which is crazy. Proposed solution: on line 1471 of wp-includes/formatting.php (as found in 3.4.2), change: {{{ $ret = preg_replace_callback( '#([\s>])((www|ftp)\.[\w\\x80-\\xff\#$%&~/.\-;:=,?@\[\]+]+)#is', '_make_web_ftp_clickable_cb', $ret ); }}} by removing the ""ftp"" case, hence: {{{ $ret = preg_replace_callback( '#([\s>])((www)\.[\w\\x80-\\xff\#$%&~/.\-;:=,?@\[\]+]+)#is', '_make_web_ftp_clickable_cb', $ret ); }}} The function _make_web_ftp_clickable_cb should then be renamed by removing ftp_, since the case of turning FTP hostnames into clickable HTTP links would have been removed.",defect (bug),new,normal,Awaiting Review,Formatting,2.0.4,normal,,,,
