SMTP with Exchange 2003

[jumpig]

As reported in CI forum (http://codeigniter.com/forums/viewthread/203230/), I get a timeout error sending email through Email.php vs Exchange 2003.
On the HELLO message phase, the message sent is:
EHLO my.webserver.name

Sending this message manually on the server via Telnet the answer I get is

250-my.exchange.server.name Hello [192.168.215.216]
250-TURN
250-SIZE
250-ETRN
250-PIPELINING
250-DSN
250-ENHANCEDSTATUSCODES
250-8bitmime
250-BINARYMIME
250-CHUNKING
250-VRFY
250-X-EXPS GSSAPI NTLM LOGIN
250-X-EXPS=LOGIN
250-AUTH GSSAPI NTLM LOGIN
250-AUTH=LOGIN
250-X-LINK2STATE
250-XEXCH50
250 OK

In the web application I get a timeout error (line number around 1839) when the following command is executed:
fgets($this->_smtp_connect, 512)

Anybody out there having access to MS Exchange 2003 in order to confirm this?

There's a post on that forum thread suggesting that changing the CRLF value solves this problem - if so, we should consider this a configuration issue.

I've got access to Ex2003 so I'll do some testing now...

Confirmed, adding:

$config['crlf'] = "\r\n";
$config['newline'] = "\r\n"; 

doesn't hang the script anymore. Therefore I don't think we need to change anything in CI.

I spent ~2 days trying to track down this fix (spent countless hours on Google and Stack Overflow). From what I've seen in blogs and forums is that other people are having this issue, and none of them have any resolution. I think this fix needs to be better publicized.
