I have configure out SBS 2003 server with IMAP capabilities to be used with an iphone.  I have enabled IMAP4, I have published the IMAP server and opened the ports on the firewall using the Connect to the internet wizard.  
We are able to receive emails, when we send they do not go through.  I have been testing it with a varity of other imap clients and I get the same results.  If I select do not authenticate before sending emails, I receive a unable to relay message. If I authenticate using the same credentials as incoming; I am always asked for my credentials again and
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: server name, Server: , Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0F

I am testing with the adminstrator and administrator password.

If someone can let me know what I need to do unitl apple gets a active sync client, I would greately appreciate it.

    I saw this article, and have tried and check all they suggested, I think it has to do with a setting in either the Exchange Server or ISA Server.

    I would try with another (preferrably fresh, or at the very least, a never renamed) account - Exchange gets a bit touchy with POP3 and IMAP logins if the account has ever been renamed.

    If the Mailbox Alias and the Username are different, it will want the username in this format -> DOMAIN\Username\Alias
