Have recently changed ISP to BT. Have always been able to send emails from my localhost for testing purposes (with previous providers) but since I've moved to BT I can't. In php.ini have set:
SMTP = mail.btinternet.com
sendmail_from = thebtinternetaddress
I've left smtp_port = 25 commented... if I uncomment this it makes no difference
When I try and send a test mail from a site on my localhost I'm getting this message: "SMTP server response: 530 authentication required - Your email could not be sent. To fix this you must make a simple change to your email (known as SMTP authentication). For advice visit www.btyahoo.com/smtp
This url is no use by the way.... I can set up SMTP autentication on outlook of course, but dont know it's asking me when I'm sending from a site!
It's really driving me nuts - any help much appreciated!
