SMTP module can not pass authentication

I have found how can I make it working,
I am not sure if it is expected but the only email account you can use for authentication HAS TO be the same account as one given on Site Information form /the same where you are putting slogan etc/

Finally I have found the solution.

As it seems problem may rise on other providers hosted sites let me explain a little.

As you can read above. The problem was that provider's smtp server did not want to pass communication.
Server closed protocol due to improperly configured email headers.

In my case if I want to route the email it HAS to follow two rules
1. I have to pass authorization /user+pass/
2. Email header HAS to be build in such a way, that address corresponding to above given account HAS TO properly included in email header.

When I realize that solution came quickly by changing header fields alignment, aspecialy by ADDING the ReplyTO field.

I've just added corresponding line below originals - not to mess original code.

So:

Just after this lines inside mail_wraper function:

// Defines the From value to what we expect.
$mail->From = $from;
$mail->FromName = $from_name;
$mail->Sender = $from;

I have added this:

//pku
$mail->RepltTo = $from; //so recipient can just press reply button
$mail->From = $from; //to satisfy server and SMTP rules
$mail->Sender = variable_get('smtp_from', ''); // to allow that mail go threw account given in SMTP module auth. fields

What is important you may have to play a little with that lines to "satisfy" your providers spam rules but finaly it's now simple.

My idea would be to include such a solution as a simple checkbox in module configuration (You may call it "Send in name of bla bla bla")
