[pmg-devel] [PATCH pmg-api/pmg-gui v3] ruledb - improve experience for non-ascii tests and mails

[Dominik Csapak]

all in all works mostly well,
tested various weird emails with various rules
that include emojis/non-ascii characters

(weird mails as in a mix of smtputf8,mixed charsets and quoted-printable fields
with mixed encodings, with and without non-ascii characters in the
sender/recipient)

things that did not work and need to be fixed if we want to apply this:

* LDAP, you mentioned it, but it fails in a really non obvious way
   and drops mails currently
* user wl/bl from the quarantine interface
   (some en/decode is missing, and garbage reaches the user lists)

things that worked in my tests:

* sending emails (with/without smtputf8)
* quarantining mails
* notication/modify/header/disclaimer/etc. with non-ascii characters
* various what/who objects with non-ascii characters
* greylisting with non-ascii characters in sender/recipient
* modifying user wl/bl
* matching user wl/bl
* log tracker
* statistics

i did find some things to note in the individual patches, i'll answer there
