Josh,
I need a bit of explanations for the concern created by people who forward their domain to sg. Two questions, please.
1. When such a forwarding takes place, can we find anything in the headers that indicates it's a forwarding?
2. Say I am a mailing list admin.. I have, among my subscribers, one person who is
john.10.doe@SomeDomain.com. Unbeknownst to me, John Doe owns SomeDomain.com and redirects it to sg.
Now, in this scenario, the SomeDomain.com mail server is going to receive an email from the mailing list. What will that email's To:, cc: and bcc fields contain? Will they contain all the addresses of subscribers in SomeDomail.com (i.e., one)? Or will you also see possibly unrelated email addresses in these fields?
Thanks for the answers.
