I have a user who doesn want to receive any more email from Bugzilla. How do I stop it entirely for this user?
The user can stop Bugzilla from sending any mail by unchecking all boxes on the ‘Preferences’ -> ‘Email Preferences’ page. (As of 2.18, this is made easier by the addition of a ‘Disable All Mail’ button.) Alternately, an administrator can disable all bugmails for this user from the administrative pages. This will override their personal preferences, and they will never be sent mail again.

Alternately, you can add their email address to the data/nomail file (one email address per line). This will override their personal preferences, and they will never be sent mail again.
