Purodha:
Then I found that there is a "user page" in
confluence which
displays an e-mail address of mine, which I thought I had entered
only in order to retieve a forgotten password, if need be.
It does show the e-mail address, even while I am logged out.
That means, the e-mail address is being published to the world.
i disabled public display of email addresses in jira and confluence.
