Email collection methodology

    Question

  • In our SME we're running SBS 2003 Premium R2 and are currently collecting mail with the POP3 connector.  We have just one global mailbox username@btconnect.com hosted by our ISP (British Telecom) with all our domain email addresses aliased against this mailbox and of course individual domain email resolution by our Exchange Server.

    I've always preferred this method over SMTP as if our server goes down or our broadband connection fails (both of which happen occasionally) we can at least retreive all mail by the ISPs Web Mail elsewhere.

    British Telecom are now migrating to Microsoft 365 for email hosting but Microsoft won't allow anything other than username@ourdomain.co.uk as the primary mailbox.

    So 2 questions please:

    Do most small businesses stick to POP3 retreival for the reasons we do?

    Will SBS 2003 work with a global POP3 mailbox of the same domain name as the local mailboxes it resolves to?

    Many thanks

  • Can't say what most small businesses do.  Many just use Outlook and pop3 and don't have an exchange server.  However, if you have an exchange server smtp is the way to do this.  The pop connector is meant to be a bridge for new setups until the smtp pieces are in place.

    The issue with the mail server or the broadband failing is easily overcome with anyone of several third parties that will collect and hold your mail until the connection/server is restored.  Some, not all, of these will allow web mail reading of the mail in the meantime.

    Regarding Q2:  Exchange server is meant to be used as a mailbox for each user.  afaik, there is no mechanism to allow mail addressed to king.george@buckinhampalace.gov to be accepted if there is no user there named king george unless king george is an alias attached to the user prime.minister@, or some other "real" user.

  • Hi,

    As we know, A global mailbox is a single POP3 mailbox account at your ISP designated to receive all e-mail sent to your company or domain. E-mail sent to a domain is identified by the e-mail domain name, which is used as the e-mail address for users who send e-mail to the Internet. When POP3 e-mail is downloaded for a domain, Exchange will read the recipients on the To and Cc lines of the message, and then forward the message to the correct Exchange mailboxes.

    Towards the pure Exchange server environment, the global mailbox is not necessary here to send/receive emails. Users could send/receive emails directly without downloading. So that’s different point between the POP3 and MAPI.

    Be default, there is only one primary domain (ourdomain.co.uk) included. However, it seems that there is another domain named btconnect.com with mailboxes hosted. I think you could add a secondary domain and set the domain federation in Office 365. You’d better ask your inquiry about Office 365 in the following link:

  • Thanks Larry. We have Exchange mailboxes for each user. Didn't realise we could have a secondary MX record for server downtimes so will go SMTP from now on.
