postfix: update to 3.4.9

upstream changes:
-----------------
 Fixed in all supported stable releases:

    Bug (introduced: Postfix 3.1): smtp_dns_resolver_options were broken while \ 
adding support for negative DNS response caching in postscreen. Postfix was \ 
inadvertently changed to call res_query() instead of res_search(). Reported by \ 
Jaroslav Skarvada.

    Bug (introduced: Postfix 2.5): Postfix ignored the CONNECT macro overrides \ 
from a Milter application. Postfix now evaluates the Milter macros for an SMTP \ 
CONNECT event after the Postfix-to-Milter connection is negotiated. Problem \ 
reported by David Bürgin.

    Bug (introduced: Postfix 3.0): sanitize (remote) server responses before \ 
storing them in the verify database, to avoid Postfix warnings about malformed \ 
UTF8. Found during code maintenance.
