Bug #16655 Updated: Function for checking if email-adress is valid

ID: 16655 Updated by: hholzgra@php.net Reported By: metz@speedpartner.de Status: Closed Bug Type: PEAR related Operating System: Linux PHP Version: 4.1.2 New Comment: a public mail server for a domain that does operate *without* MX records does not deserve to be taken serious IMHO how do you implement fallback servers without MX records? and even if you say and A or CNAME record is enough, how do you check that the machine with that ip does really accept mail? by probing the SMTP port all the time? hartmut@www.six.de might be a legal address by the CNAME rule, but i can assure you that mail to that address will never reach me so no MX -> no mail makes sense IMHO Previous Comments: ------------------------------------------------------------------------ [2002-04-17 20:32:40] cox@php.net It's wrong to only check the MX address as many domains don't have it (it's not a requirement). The CNAME has to be checked too. ------------------------------------------------------------------------ [2002-04-17 16:36:33] richard@php.net There's already Mail/RFC822.php ------------------------------------------------------------------------ [2002-04-17 16:19:24] mfischer@php.net This belongs into PEAR (if at all). ------------------------------------------------------------------------ [2002-04-17 12:36:23] metz@speedpartner.de you don't know how happy I am ;)) ------------------------------------------------------------------------ [2002-04-17 10:23:16] cynic@php.net everything's possible, but PEAR is part of the "standard repertoire", so you should be happy. :) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
