* postfix ≥3.0: don't advertise SMTPUTF8 support.Guilhem Moulin2018-12-061
| | | | | | | | | | | | | | | | | We're relaying messages to our LMTP daemons (Dovecot, Amavisd) and some downstream SMTP servers, not all of which are under our control. Forwarding messages with UTF-8 envelope addresses or RFC 5322 headers yields undeliverable messages, and the bounces make us a potential backscatter source. So it's better to disable SMTPUTF8 at this point. Cf. also http://www.postfix.org/SMTPUTF8_README.html and https://unix.stackexchange.com/questions/320091/configure-postfix-and-dovecot-lmtp-to-receive-mail-via-smtputf8 . See also upstream's comment at https://marc.info/?l=postfix-users&m=149183235529042&w=2 : “Perhaps SMTPUTF8 autodetection could be more granular: UTF8 in the envelope is definitely problematic for a receiver that does not support SMTPUTF8, while UTF8 in a message header is less so.”
* Upgrade 'ikiwiki-pandoc' to v0.5.1.Guilhem Moulin2018-12-061
| | | | | https://raw.githubusercontent.com/sciunto-org/ikiwiki-pandoc/v0.5.1/pandoc.pm Currently at commit 9292e45cea1be120adb3babd5b835b547f4c825a .
* Roundcube: improve serving of static resources.Guilhem Moulin2018-12-061
| | | | | | | | | | | | | | | We only serve whitelisted extensions (css, js, png, etc.), and only for some selected sub-directories. Access to everything else (incl. log files and config files) is denied with a 404. This is unlike upstream's .htaccess file, which blacklists restricted locations and happily serves the rest: https://github.com/roundcube/roundcubemail/blob/master/.htaccess#L8 To find out which extensions exist on the file system, run find -L /var/lib/roundcube/{plugins,program/js,program/resources,skins} -type f \ | sed -n 's/.*\.//p' | sort | uniq -c
* DKIM: also include the "d=" tag in key filenames, not only the "s=" tag.Guilhem Moulin2018-12-053
| | | | | While the combination of "s=" tag (selector) & "d=" tag signing domain maps to a unique key, the selector alone doesn't necessarily.
