As you suggest, that change does not work . . . sendfax just returns. With -v, we can see what's up:

[root@ducent etc]# faxstat -vs
Trying localhost (127.0.0.1) at port 4559...
Connected to localhost.localdomain.
420 localhost.localdomain server cannot initialize: Could not create client/26393: No such file or directory

Syslog logs:

Mar  5 16:04:31 ducent HylaFAX[26393]: connection refused (Could not create client/26393: No such file or directory) from localhost.localdomain [127.0.0.1]

strace of faxstat with no -v flag:
