Summary
Identifying the source of email spoofing reports sent to spoof@ebay.com is a complex process involving various strategies. It starts with understanding that eBay uses spoof@ebay.com to collect reports on fraudulent emails. Experts suggest considering factors like mentioning eBay in the email content or recipients actively reporting the messages. The email might be auto-forwarded, prompting the use of VERP (Variable Envelope Return Path), opaque tokens, or custom header fields to identify the recipient. Chunking sends and analyzing feedback loops can help isolate problematic segments. Monitoring complaint rates and maintaining a good sender reputation are crucial. Implementing double opt-in, suppression lists, and tools like Return Path provide additional support. Examining campaign IDs and analyzing email headers for clues are also recommended. Finally, establishing SPF, DKIM, and DMARC helps prevent spoofing in the first place.
