Xcode Server notifies developers via e-mail (sadly no Jabber support yet) about the state of its integrations. In the default settings, Mavericks Server directly tries to send these messages. If your Xcode Server runs on a regular dialup DSL line, these messages will most likely be bounced as spam. 
To get it to work one needs to activate the relay option in the Server.app > Mail settings  with the credentials of your e-mail ISP.
But additionally I had to issue the following commands in Terminal.app to make it work:

sudo postconf -c /Library/Server/Mail/Config/postfix/ -e "smtp_sasl_security_options = noanonymous"
sudo postfix reload
sudo postsuper -r ALL
