SME9 is still Alpha and has bugs. As Stefano suggested, you can click on the Bugs link above and report the problem ("raise a bug").
However, you need to give a lot more information about your system and what your settings are so someone can help.
By the way, are you trying to collect mail as "root" from the server - perhaps your problem is a password issue and the root account was locked. Reboot and see if you can logon at the console (ie physically at the server).
Root can certainly logon via ssh - many people regularly administer remote SME systems using something like puTTy and ssh.
In the meantime, since SME is all new to you, try SME 8 and get used to it, then give SME 9 another go.
Cheers and good luck.
