Why was I automatically removed from a list?
While there are many reasons why you might have been removed from a list, recently we have been seeing subscribers automatically being removed
from a list due to a new spam filter process which evaluates emails that are being seen multiple times through our email core.
More explanation:
You may have a unique setup, in that you have email forwarding for PENNKEY@upenn.edu pointed to your Zimbra email account PENNKEY@zimbra.upenn.edu,
and then your Zimbra email account is being forwarded to an Exchange email account PENNKEY@exchange.upenn.edu for final delivery.
This causes any email that comes in to PENNKEY@upenn.edu to recurse through two different email services, including the spam filter multiple times.
How do I know if I'm affected?
You will have an account on both UPenn Zimbra service and UPenn Exchange account.
Steps that you may need to take to resolve this problem:
- The subscriber PENNKEY@upenn.edu forwarding is change to use their Exchange account
- The subscriber email is updated in Listserv to point to their Exchange email account
- The Auto-Delete subscribers option is turned off in Listserv per list owner
Options B and C will only quiet the problem in Listserv, and not other email providers trying to send to you via PENNKEY@upenn.edu.
If you feel this may have happened to you, please email listserv-help@isc.upenn.edu so that we can help assist in the remediation.
