Hello, There are the domain registrars who have email forwarding for the user's domains.
Do you know the forwarding happens against the "to:" address in the message's header, or in SMTP's talking session (the rcpt to: command)? I asked this question b/c I saw some mailing lists were not forwarded correctly. Those messages' "to:" addresses are the list address, so they were not forwarded by the rules setup by users. Thanks.
