 From doc/install-murder.html:

Additionally, you will need entries in imapd.conf to indicate the proxy 
auth name and passwords (if you are using a SASL mechanism that requires 
them) to the backends, for example, if your backends are 
mail1.andrew.cmu.edu and mail2.andrew.cmu.edu with passwords of foo and 
bar, and an auth name of murder:

mail1_password: foo
mail2_password: bar
proxy_authname: murder
