How to configure WAMP (localhost) to send email using Gmail?

Gmail servers use SMTP Authentication under SSL or TLS. I think that there is no way to use the mail() function under that circumstances, so you might want to check these alternatives:

• PEAR::Mail
• phpMailer
• Nette\Mail

They all support SMTP auth under SSL.

You'll need to enable the php_openssl extension in your php.ini.

Additional Resources:

• Mailing using Nette\Mail

If you open the php.ini file in wamp, you will find these two lines:

smtp_server
smtp_port

Add the server and port number for your host (you may need to contact them for details)

The following two lines don't exist:

auth_username
auth_password

So you will need to add them to be able to send mail from a server that requires authentication. So an example may be:

smtp_server = mail.example.com
smtp_port = 26
auth_username = example_username@example.com
auth_password = example_password

i know in XAMPP i can configure sendmail.ini to forward local email. need to set

smtp_sever
smtp_port
auth_username
auth_password

this works when using my own server, not gmail so can't say for certain you'd have no problems

I'm positive it would require SMTP authentication credentials as well.
