Hi! Is it possible for me to use pop3 connector and hav exchange delivered mail directly?
I use pop3 connector today and have smtp/pop3 ports (inbound) closed on the firewall. Our ISP has offer us to point a first MX record to our static (public) ip and use thier own as second. Therefore all mails will be delivered to them, if our server is down in any reason.
I want to have pop3 connector still downloading mails from there pop3 accounts even though mail going directly to our Exchange Server. This would work like a fail over. If our system (or Internetline) is going down, then our ISP's mailserver is picking up the mail, for our POP3 connector to download instead.
Is this possible? Can I on any way try to e-mail our Exchangeserver directly and get that mail delivered to corresponding mailbox without stopping anything who works today? Like e-mailen name.name@ourpublicipadress or something? I've tried but it doesn't deliver.. (port 25 is open inbound)
