A previous question asked about the "No available releases found" warning that Drupal shows in the Modules Update page. An answer said that this is caused by the fact that CiviCRM doesn't use Drupal's release infrastructure.
In any case, Drupal still emails me with the warning that "There was a problem checking available updates for your modules or themes."
Given that I like my sites to run without errors, the OCD part of me cringes at this. How might I correct this so that Drupal and I are happy?
