I can't mail to another Servers (or domains)

I can mail to [e-mail] when my php.ini settings like this

[mail function]
; For Win32 only.
SMTP = mail.xxx.com

; For Win32 only.
sendmail_from = [e-mail]

BUT I CAN'T MAIL yahoo.com, hotmail.com....(other domains)

My Platform:
IIS 5.0
Win 2000 Pro
Php 4.2.3 (ISAPI)

[e-mail]

other domains are you saying like mail.com and all those big Mail Clients. Or what. Most of the time big Mail Client Sites Hotmail, Yahoo. Have some thing to detect mail from site. I dont know why. But they do.

Is xxx.com set up to allow relaying from the IP of your server?

Most mail servers do not work as open relay, because if they did they would get used by spammers. Most mail servers are configured to only accept mail for their domain (eg. mail.xxx.com would only accept mail addressed to @xxx.com). In the case of an ISP, the mail server would be configured to also relay mail to any email address from users whos IP address is in the dial-up address pool.

Are you sure the mail server is configured to relay mail from the IP of the web server?

Try setting the sendmail_from and SMTP server settings in the script.

ini_set("SMTP","mail.yourisp.net");
ini_set("sendmail_from","[e-mail]");
