Fundraising tech/Failmail zoo

A guide to the species of failmail encountered in our systems

Error validating Amazon message. Firewall problem?
Our IPN listener receives messages from Amazon Simple Notification Services when donors send an Amazon Pay donation. Each notification contains a URL for a certificate, and part of the Amazon Pay SDK's logic retrieves that cert and uses it to check the signature. This failmail means something went wrong getting the cert.

There is an IP address in this failmail, but it's not the one we're trying to connect to and failing. The IP logged for all Amazon SNS messages is the SOURCE of the notification, not the IP address we try to contact to get the cert. To find the offending IP address, you will have to ssh into thulium / frpig1001 and try to fetch the cert from the URL mentioned in the log.

Fundraising ops will have to make sure that IP address is whitelisted in IPtables on thulium / frpig1001.

run-job: Get recipient data from Silverpop failed with code 1
This happens almost daily with error message 'Login Failed'. Should we be retrying logins? Or is this usually during Silverpop's planned maintenance?
