smtp / mail function problem

[ced_gdn]

Hello

I'm trying to use the mail function with my own local mail server in a groupware tool written in php.

• When I use an external SMTP server (the one of my ISP) everything’s fine : I can send and retrieve mails from my external mailboxes.
• When I use my local mailboxes through the client of my mail Server everything is ok
• But when I’m trying to use my my mail server with my local
  mailboxes through Php : I can’t send any mail (retrieving mails works fine).

I’m using Win2000 Server, PHP 4.3.1, IIS 5.0, Imail Server 8.0.
I've removed the SMTP server of IIS to avoide conflicts.
I have a Dynamic IP so I didn’t configure any DNS.
Here is my php.ini config :
[mail function]
SMTP = localhost
;SMTP = 127.0.0.1 ;I tried both
smtp_port = 25
sendmail_from = [e-mail];

Do you have any idea of how to make it work ?

Thanks in advance

I thin that in platce of SMTP = localhost you need to use your SMT server like I do with mine www.blah.com chack your mail account

Ok works fine now.
The php.ini file hasn't change.
I thing the problem was coming from Imail Server
