as mantioned in "Practical JIRA administration" book / section 6.4:
Once a user leaves an organization, their email address will eventually become invalid and may cause "bounce" errors in the JIRA log files. To avoid this, change the top-level domain in the user’s email address from <tt>.org</tt> or<tt>.com</tt> to <tt>.invalid</tt>, which is the official way to mark an email address as invalid (RFC 2606).
when i set email address im my Crowd to user@example.invalid - JIRA is still trying to email those users and i get bounced emails.
has anyone done the same in their environment? does .invalid work?
I can think of another solution of setting their email to noreply@example.com, but I would like to keep their emails mostly intact, just in case they need to be reactivated in the future.
thanks
