Since it’s common for wildcard~ish systems to prefer concrete objects over
wildcards, and aliases can be broad-wildcards (think catchall, %@xxx.tld), it
may be more intuitive for users that user-names rank higher than aliases. This
makes it impossible for user-names to be unreachable, since they can be
completely overridden by a catchall otherwise.
This changes default behavior, and is not configurable.

As discussed with hoellen on matrix, since postfix indeed supports including
the recipient delimiter character in a verbatim alias, we should support so too
— and handle its precedence correctly. The clearer and simpler formulation of
the precedence-clauses are credit to @hoellen. Thanks!
This fixes delivery to an alias minus recipient delimiter in cases where a
wildcard alias would also match. For example,
* foo@xxx.tld
* %@xxx.tld
Sending to foo+spam@xxx.tld would get eaten by the catchall before this fix.
Now, the order of alias resolution is made clearer.

CVE-2017-18342
Vulnerable versions: < 4.2b1
Patched version: 4.2b1
In PyYAML before 4.1, the yaml.load() API could execute arbitrary code. In other words, yaml.safe_load is not used.
Since postfix now asks us for the complete email over podop, which
includes the recipient-delimiter-and-what-follows not stripped, we need
to attempt to find both the verbatim localpart, as well as the localpart
stripped of the delimited part ….
Fixes#755
The init script was pushing an application context, which maked
flask.g global and persisted across requests. This was evaluated
to have a minimal security impact.
This explains/fixes #738: flask_wtf caches the csrf token in the
application context to have a single token per request, and only
sets the session attribute after the first generation.
This will make network configuration and host based authentication
more robust, across different deployment platforms.
The options `RELAYNETS` and`POD_ADDRESS_RANGE` are kept for compatibility.
However, their usage have become optional.
At present postfix checks this view for matches in the domain table and is used to accept/deny messages sent into it however it never checks for matches in the alternative table.
Fixes#718
