[Tutor] cyrus interaction

[Cerulean Rodent]

So this time I'm trying to automate the process of adding users to the Cyrus server. 
A sample script that doesn't work: 

x = os.popen("cyradm -user mailadmin localhost")

x.write("mypassword")

So I can't even make it log on to cyradm. All I get in response is the following 
message: 

application-specific initialization failed: error flushing "file1": broken pipe

Now where is the heinously idiotic mistake that I'm not aware of making? Ideas, 
anyone?

Cheerio,
