I have a client running SBS 2003. He has 6 Office Workers downloading POP3 mail from ISP using pop3 connector, no problem. However he has another 12 remote workers with pop3 mail accounts on the same domain name downloading mail direct from ISP, not from Exchange Server. My client running from Exchange is having mail sent to the 12 remote workers bounced back as undeliverable. My assumption is that Exchange is bouncing the mail as the 12 are not mailboxes setup in Exchange for that domain so is not sending to ISP for delivery, could anybody help me on this.
