I read that Omnimix can download "dummy messages" when downloading
my own messages, in order to confuse an adversary.
But what is the tab to use?
"It's obvious, that by only downloading relevant messages
you give valuable information to an adversary. That's why
OmniMix offers you to fetch randomly some non-matching messages
as well. At 'Dummy Messages' you have to specify the approximate
number of 'dummy' messages to pick for every valid nym message.
Set it to '0' for only downloading valid messages, or better to
a higher number to leave an adequate amount of wrong tracks."
