With `CHUNKING`set as a capability, nginx advertises this capability to
clients at a stage where the SMTP dialog does not seem to be forwarded
to the proxy-target (postfix) yet. Nginx' SMTP parser itself does not
support the `BDAT` command issued as part of a chunke-d dialog. This makes
Nginx respond with a `250 2.0.0 OK` and close the connection, after the
mail-data got sent by the client — without forwarding this to the
proxy-target.
With this, users mail can be lost.
Furthermore, when a user uses a sieve filter to forward mail, dovecot
sometimes chunks the forwarded mail when sending it through `front`.
These forwards then fail.
Removing `CHUNKING` from the capabilities fixes this behavior.

Because basically every MTA out there uses opportunistic TLS _in
the best case_, it's actually counter productive to use such strict
settings.
The alternative to a handshake error is often an unencrypted submission,
which is basically the opposite of what strict ssl_protocols and
ssl_ciphers tries to achieve.
Even big and established providers like Amazon SES are incompatible with the current
settings.
This reverts commit 2ddf46ad2b.

1538: Introduce environment variable to control dovecot full-text-search r=mergify[bot] a=tremlin
## What type of PR?
Enhancement
## What does this PR do?
In #1320 a full-text-search feature was enabled in Dovecot by default. Since this can have a big impact on performance, I think it's preferable to offer an option to disable the feature if it is not needed. This PR doesn't change the default behavior (FTS on).

1501: In setup/flavor, change DMARC RUA and RUF email default settings r=mergify[bot] a=ofthesun9
## What type of PR?
bug-fix
## What does this PR do?
This PR changes the default value used to set DMARC_RUA and DMARC_RUF:
DMARC_RUA and DMARC_RUF defaults will reuse the value defined for POSTMASTER,
instead of 'admin' as previously.
Please note that the setup tool doesn't allow (yet?) to define dmarc_rua nor dmarc_ruf, so the default value is indeed used for the time being.

1399: Remove SPF type SPF record #1394 r=mergify[bot] a=bladeswords
As mentioned in #1394 - In accordance with RFC 7208, offer only TXT RRs for SPF.
Agree with @Nebukadneza - but not sure how to go about telling people to remove the old record...
## What type of PR?

Removes the recommendation to add a SPF RR for SPF records, as this is no longer RFC complaint and often causes issues to maintain two records.

1389: Prefer specific alias over wildcard, regardless of case r=mergify[bot] a=Nebukadneza
## What type of PR?
bug-fix
## What does this PR do?
Since direct addresses (not aliases) are case-insensitive since a while,
it makes sense for aliases to behave the same. Up until now, a wildcard
alias could trump a alias not-matching-the-case of the incoming address.
This clarifies this behavior.
## Notes
I realize that the if-hell down there isn’t nice. What it is, however, is quite clear and easy to read. I’m hoping that if anyone ever gets confused in the future, this will make the current behavior transparent. For me, that was more important than a minimal amount of statements/branches …
