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
server certificate verification failed for example.org[A.B.C.D]:25: num=62:hostname mismatch
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?=
Replace \r\r\n in literal.eml test with \r\n
to make `test_filtermail_no_literal_packets`
actually reach `check_openpgp_payload()`
and make `check_openpgp_payload()` more strict.
unbound-control is not installed out of the box
and even once installed `flush_zone` does not seem
to work reliably.
Instead of trying to flush the cache from unbound,
we now query authoritative nameserver directly using `dig`.
I wanted to add `COMPRESS=DEFLATE`,
but it should be added only for sessions
that are logged in because `COMPRESS`
command does not work before logging in.
Dovecot already does it correctly
if we don't overwrite the capability string.
* Improve README for first setup
