Just a side note: these proxy_set_header directives are useless.

With "-" here, loading the configuration is expected to fail with
an error like:
nginx: [emerg] require_pv("mailauth.pm") failed: "Can't use bareword ("ip") as
a HASH ref while "strict refs" in use at /path/to/mailauth.pm line 13.
If the code provided exactly as used, likely you are testing with
some older version which does not have this bug.
In no particular order:
- make sure to reload nginx configuration after changing the perl
module;
- try looking into nginx error logs, it might have helpful information.
Note well that using embedded perl for potentially blocking
lookups in the LDAP database might not be a good idea. Quoting
http://nginx.org/en/docs/http/ngx_http_perl_module.html:
: While the Perl module is performing a long-running operation, such
: as resolving a domain name, connecting to another server, or
: querying a database, other requests assigned to the current worker
: process will not be processed. It is thus recommended to perform
: only such operations that have predictable and short execution
: time, such as accessing the local file system.
