Title:
A cron task to periodically clear the VERP bounce counts
Status in Mahara:
In Progress
Bug description:
Mahara has a VERP system to disable email addresses that have been
bouncing. "Bounces_min" and "Bounces_ratio", and it disables an email
when it has received more than "bounces_min" bounces and the ratio of
bounced messages to all messages sent is greater than bounces_ratio.
The thing is, these are *lifetime* numbers, and never get reset. This
poses some difficulties once a site has been around for a few years,
like mahara.org. We have some email addresses that have received
thousands of messages. So, if we set bounces_threshold to something
like the default "0.2" setting, then if one of those longtime
addresses become invalid, we would continue to send hundreds of
messages to it before we got around to disabling it. On the other
hand, if we set bounces_threshold to 0, then we have the problem that
the bounce count is cumulative and never gets reset. So, if we leave
it at the default 5 emails, I could get disabled due to one bounce
every three months over the course of a year and a half.
Really, whether to disable someone's email should be based on how much
it has been bouncing *recently*. So what we should do is add a cron
task which sets the artefact_internal_profile_email.maillsent and
artefact_internal_profile_email.bouncecount columns back to 0
periodically.
