How to send email from IIS PHP using gmail SMTP?

Question

How can I use IIS6 PHP with gmail smtp. I am running windows 7.

My php.ini file has on the bottom

SMTP = smtp.gmail.com
smtp_port = 25
auth_username = [username]
auth_password = [password]
sendmail_from = [username]@gmail.com

When I try it in php, I get the error:

: mail(): Failed to connect to mailserver at "smtp.gmail.com" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in on line ：mail（）：无法连接到“smtp.gmail.com”端口25的邮件服务器，验证php.ini中的“SMTP”和“smtp_port”设置或使用 ini_set（）第行的

Right now, the server is on my home wifi network (router, modem). However if I connect my server to my LTE phone data plan, then it works fine.

Does anyone know what the problem is? Maybe a firewall thing?

Thanks

In this particular circumstance, I suspect your LTE provider is firewalling port 25.
