SRS_EXCLUDE_DOMAINS only works with comma-delimited

[AgyarJanos]

From postsrsd conf:

Exclude additional domains.

You may list domains which shall not be subjected to address rewriting.

If a domain name starts with a dot, it matches all subdomains, but not

the domain itself. Separate multiple domains by space or comma.

SRS_EXCLUDE_DOMAINS=.example.com,example.org

But in my testing a space-delimited list did not actually work.
