- Before proceeding with installation of Python dependencies, check
whether the 'gcc' command is available by running it with the
--version argument. If it is not available, print a helpful message
and exit.
- For the current set of Python dependencies, without GCC, the build
process fails when building the crypt-r package. According to the
error message, on my system the exact command it tries to run is
'x86_64-linux-gnu-gcc', but rather than depend on this variant
specifically, the script checks for the generic 'gcc' command, so as
to avoid coupling the check to an architecture or operating system.
Similar problems arise if we attempt to check for packages by name;
the compiler binary is provided by 'gcc-11', but the symlinks that
provide the unversioned commands (as used by the Python build) come
from a package named 'gcc'. Trying to be too precise in what we
check for could lead to unnecessary failures in some environments,
or become a maintenance challenge in the future. For that reason,
this change simply attempts to run 'gcc' and uses that as a
probably-sufficient proxy for having what the Python package install
will need.
High-security mode could be configured
to handle more connections by increasing process_limit,
but has problems logging in many users at once after
each Dovecot restart or config reload.

Otherwise email providers which allow to bring your own domain
and use the same IP addresses for all customers
send wildcard certificate instead of the correct one
and Postfix refuses to connect with an error

It does not work because of `smtpd_proxy_filter`
forwarding the message to filtermail
and we cleanup the message once
filtermail reinjects it on port 10025.
`authclean` cleanup server is used by
reinjecting smtpd running on localhost:10025 by default.
It runs after filtermail
and currently removes `Received` header
to avoid leaking IP address.
Can as well be used to replace `Subject` lines
with `Subject: [...]`.
If there are multiple `Subject` lines,
all of them should be replaced.
This allows us to avoid dealing with
localized subjects, including SecureJoin
messages `vc-request` and `vg-request`
which can have Subject lines like
Subject: =?utf-8?q?Nachricht_von_nrn178fi4=40nine=2Etestrun=2Eorg?=
