This question already has an answer here:
Is there a way I can tell Drupal not to notify me about a particular version of a module? For example, if it isn't security related and I choose not to update one module but would like to receive notifications about other modules (or future versions of the module in question)?
The Drush command from one of the answers to this question is close to what I want except if there are future security updates I would still like to know about it, just no more notifications for this particular version.
drush pm-updatecode --lock=module_to_ignore
