I feel like this is a stupid question but:
I have a test environment set up where I need to enable SMTP basic authentication with IIS. I have a Win2k3 r2 server as a DC in its own windows domain called testdom.local. I also have the MS pop3 server set up with the testdom.local domain on that server. I have a windows account called "simon" on that domain and a mail box set up on the pop3 service.
With anonymous access set up on the IIS smtp server, I can send an email from a client to the server which will arrive in the simon mailbox. If I turn on basic authentication on the SMTP server, I can not get the mail client (outlook 2003) to authenticate.
I have followed what is said here: http://support.microsoft.com/kb/324285
I have tried:
- the domains "testdom" and "testdom.local" in the default domain box in the SMTP authentication properties.
- Using the logon names "simon", "firstname.lastname@example.org" and "testdom\simon" in the logon properties on the mail client.
- I have tried specifying smtp authentication using "use same settings as my incoming server" and manually specifying the account details.
What am I doing wrong? I feel like I am missing something really obvious!
Please note: This is a test environment, I have a requirement to use SMTP basic auth, so I am not interested in using any other authentication option. I have made sure Integrated Windows and SPA auth are turned off on client and server, and I have double checked the password is right because the pop3 works to collect the mail.
