Auth on sbs2008 smtp

Posted on 2011-02-18
Last Modified: 2012-05-11
We have a sbs2008 server. Last night it did some hosted and no longer gets incoming email. I have done a test and when telnet  using port 25 into it it asks for a password. Is there an easy way to remove this.

Have you checked your router/firewall to make sure port 25 is still forwarding to the correct IP address?

Check these services are running:

Yes it still forwards. I have tested public and private address of server and still asked for password.
Damn microsoft updates.

I seem to recall this is a problem with the authentication mode on Companyweb, and you need to change the authentication method rather than recreate the web site.

This URL may help:

I have an article here on how toresolve the common causes.  You might want to try the kernel mode authentication first:

Go into the SBS Console and change/update all users security settings.

I now have it working.
If anyone else every has the issue open exchange control panel and go to
Server config > hub transport and adjust the default transport at the bottom of the screen.
The on the auth tab untick erverything except TLS and basic auth.

Will then work fine.

ms updates must have added additional security over night.
