note 90300 added to function.mail

RFC 2822 has been obsoleted by RFC 5322 (http://tools.ietf.org/html/rfc5322). Not much has changed, but if you want to quote an RFC then this is the current one. Regarding the use of regexes to validate email addresses; I wrote a short essay about it here: http://www.dominicsayers.com/isemail/ which includes some test cases to check whether your regex is validating correctly against RFC 5322. ---- Server IP: 92.48.74.199 Probable Submitter: 93.97.43.62 ---- Manual Page -- http://www.php.net/manual/en/function.mail.php Edit -- https://master.php.net/note/edit/90300 Del: integrated -- https://master.php.net/note/delete/90300/integrated Del: useless -- https://master.php.net/note/delete/90300/useless Del: bad code -- https://master.php.net/note/delete/90300/bad+code Del: spam -- https://master.php.net/note/delete/90300/spam Del: non-english -- https://master.php.net/note/delete/90300/non-english Del: in docs -- https://master.php.net/note/delete/90300/in+docs Del: other reasons-- https://master.php.net/note/delete/90300 Reject -- https://master.php.net/note/reject/90300 Search -- https://master.php.net/manage/user-notes.php
