Roundcube on Windows Server 2003

[jam57t]

I'm using Windows Server 2003 Enterprise IIS 6 and have been working on this for several weeks when time permits. When I run PHPinfo my setting show up fine which tells me PHP is working. I also have ISAPI web extension enabled. I've modified my SMTP setting various ways with the main.inc.php file and I assume when I'm incorrect I get "failed to connect to IMAP server". I'm trying to determine if my problem is with a setting in main.inc.php or my php.ini file. However when I think my SMTP setting is correct I recieving mail fine but when I send I get "!Failed to send message." I've checked for hmail errors and it all looks good. I've also notice I no longer get error logs from roundcube... I'm stumped can someone please help point me in the right direction??
Thanks

alter your php.ini & check if imap extension is on, dont forget to restart the server for changes

That works great, I completely overlooked or never would have thought of it. It's coming together and a big thanks to you....
