Launch console, with shift+ctrl+i and copy and paste in:
document.location.pathname = '/watch_popup';
Now HTML video playback should work, without Flash.

There is too much configuration. There is too much state. There are too many options. There are too many dot files. Stuff should just work.
— Rob Pike (@rob_pike) July 26, 2013The most minimal Dovecot IMAP configuration I could find is:
log_path = /var/log/dovecot.log
ssl = no
passdb {
driver = pam
}
userdb {
driver = passwd
}
The default dovecot.sample sucks (>1000 SLOC!!) and so does http://wiki2.dovecot.org/QuickConfiguration.
You need log_path or you won't be able to understand why dovecot fails to
come up with dovecot.service: main process exited, code=exited, status=89/n/a
typically seen via journalctl --full -f -u dovecot.
The Dovecot configuration format is a little painful. This won't work:
passdb { driver = pam }
Nor this:
passdb {
driver = pam }
Feel free to experiment yourself between sudo systemctl restart dovecot while
tail -f /var/log/dovecot.log on a large screen.
In my Archlinux system, by default email sanely ends up in ~/Maildir via Postfix handing mail over to Dovecot's Local Delivery Agent:
$ grep mailbox /etc/postfix/main.cf
mailbox_command = /usr/lib/dovecot/deliver
I could just not run the IMAP part I guess and use mutt -f ~/Maildir/.
When I use dovecot -n to get a canonical view of the configuration I get:
# 2.2.9: /etc/dovecot/dovecot.conf
# OS: Linux 3.2.0-0.bpo.4-amd64 x86_64
log_path = /var/log/dovecot.log
managesieve_notify_capability = mailto
managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave
passdb {
driver = pam
}
ssl = no
userdb {
driver = passwd
}
That managesieve... stuff is injected from installing the separate pigeonhole package btw.
My Dovecot IMAP configuration goals are:
- Have the most minimal configuration possible. Every LOC counts!
- For sent mail to be in the inbox so I can see my replies inline, in the context of a conversation like Gmail
- To get full text search search working
- To get DSPAM integrated, since I don't want SPAM and I don't want Perl on my system ideally
- To get my mailing list traffic in separate folders (I think this is where pigeonhole/sieve comes in), labelled by the listname
- To get SSL stuff working
- To be able to access my mail via Apple IOS client on my Iphone
I want to see Dovecot succeed but there are a couple of obvious problems with it:
- the moinmoin wiki sucks, no git backend. Documentation around the Web is terrible / confusing (this blog will probably make matters worse)
- Source control is in mercurial ... urgh, no one wants to work with that anymore since 2013
- No sane bug list AFAICT
- The mailing list archives are barely usable, difficult to explore or find useful information
