Store not sending some emails - please help!

[mparvan]

Hello!

I have installed OS Commerce MS2.2 at http://www.pentax.ro/catalog/default.php This was the easy part...
The problem is with sending email from the store; I know this problem has been discussed here before, I have read a lot of

messages before posting this, but I couldn't find the right solution, yet, so, pleaaaasee, I need you help!!

The store works fine, and I can send emails:
- as a customer,from the "Contact Us" page,
- as the shop owner, from the Customers > Email page and from the Tools/Send email page

Now, the problem: on registration, neither the customer, nor I receive any emails, and the same happens at the order

confirmation stage and when I update the status of an order.

However, the orders appear in the database.

I have tried everything:

- the PHP settings for the email are:
sendmail_from root@rol.ro
SMTP relay.rol.ro

-server data is:

Server Host: ATLAS (213.154.144.81)
Server OS: CYGWIN_NT-5.0 1.3.1(0.38/3/2)
Server Date: 06/27/2003 11:04:14
Database Host: localhost (127.0.0.1)
Database: MySQL 3.23.54-nt
Datebase Date: 06/27/2003 11:04:13
HTTP Server: Microsoft-IIS/5.0
PHP Version: 4.2.2 (Zend: 1.2.0)

I have configured the email settings in the Administration section:

Email transport method: SMTP (it's a Win server)
Email linefeeds: CRLF (I have also tried LF and it doesn't work)
Use MIME: false
Check email: false
Send emails: true

I have also wrote an email address to "Send extra emails to"

still... no emails.

If anyone knows what's my problem and how to fix it, please help me before I change my career...

TIA,
