The log message about service name checking is wrong.

In src/proxymap/proxymap.c, there is a mismatch between if checking condition and log message as follows:

    if (strcmp(service_name, MAIL_SERVICE_PROXYWRITE) == 0)
     proxy_writer = 1;
    else if (strcmp(service_name, MAIL_SERVICE_PROXYMAP) != 0)
     msg_fatal("service name must be one of %s or %s",
        MAIL_SERVICE_PROXYMAP, MAIL_SERVICE_PROXYMAP);

The log message uses "MAIL_SERVICE_PROXYMAP" twice, while one of these two usage should be "MAIL_SERVICE_PROXYWRITE".
