scmeeker Posted June 22, 2010 Share Posted June 22, 2010 I'm trying to get my registration form to send a confirmation email. It works and enters a record and goes through the motion but I get this error: "Warning: mail() [function.mail]: SMTP server response: 550 must be authenticated" I've set my php.ini file to be set to my SMTP server...but am just not sure what's going on. Help? Link to comment https://forums.phpfreaks.com/topic/205587-mailing-error/ Share on other sites More sharing options...
Coders2018 Posted June 22, 2010 Share Posted June 22, 2010 I'm almost certain that this is something that you have to do on your Email program. You have to tick a box allowing authentication to that port. Link to comment https://forums.phpfreaks.com/topic/205587-mailing-error/#findComment-1075816 Share on other sites More sharing options...
