I’m trying to send an e-mail from a module I’m writing, but I keep getting this error message, even when I hardcode a valid address in the call to drupal_mail():
Warning: mail() [function.mail]: SMTP server response: 550 The address is not valid in DefaultMailSystem->mail() (line 77 of C:\Program Files (x86)\wamp\www\drupal-7.0\modules\system\system.mail.inc).
How do I fix this?
This has nothing to do with Drupal but with the SMTP (simple mail transfer protocol) configuration in php.ini file somewhere in C:\Program Files (x86)\wamp\ (I don’t know exactly where because I use xampp).
There you have to look for ‘mail function’ where you can put
SMTP = smtp.server where server is the name of the server from your internet provider.
Personnaly I don’t change a thing to this because everything will work once going live.
