Campus Mailing Lists, Bounce rate too high
Information about "bounce rate too high" causes, the rate setting and resetting the notification
Possible Causes:
- The most common cause of a bounce is an invalid email address subscribed to a list. In this case, the owner should “delete” the email address from the list. More details below.
- The list server misinterprets automated replies as a bounce. While most auto replies are interpreted correctly, we’ve seen this bug in the software and have reported it to the development team, www.sympa.org.
The Setting:
Mail list owners can change the notification setting at: Admin > Edit List Config > Bounces This setting defines the bounce rate (% of subscribers bouncing) required before the sever notifies the list owner bounces exceed the set values. The default values are: warn=30%, halt=50%. More info at: https://sympadocs.web.illinois.edu/campus-mailing-lists-users-guide/list-owner-docs/the-list-owner-settings/edit-list-config/bounces/
Resetting the Bounce Rate:
To reset the bounce the bounce rate go to: Admin > Bounces. Review the email list, select the checkbox next to the email address you want to “reset” or “delete” from the list.
- If you have a large list, change the view to “500”.
- To select all email addresses click the checkbox at the top of the check box column.
