Setting connection schedules to a host

If you have continuous Internet access

    To schedule connections to a host when you have continuous Internet access:
    1 Open Mac OS Server Admin and log on to the server you want to administer.
    2 Press the Mail Services button and choose Show Host List.
    3 Select the host you want to edit and click the Edit Host button.
    Note: You cannot edit a host connected over AppleTalk.
    4 Click the Schedule tab.
    5 Make the changes you want to the Schedule settings.

If you have intermittent Internet access

    To receive e-mail from a host when you have intermittent Internet access, you need to associate your server with a backup server that has a continuous connection to the Internet. If your mail server is not available, mail is sent to the backup server. When your server becomes available for mail service, it notifies ("pings") the backup server.

    To set up a connection with intermittent access:
    1 Ask your ISP to create an MX entry on the DNS server that specifies the ISP's mail server as the backup to your mail server.
    The MX entry should list your server first and the ISP's server second:
    10 yourserver.yourcompany.com
    20 mail.your_isp.com
    MX entries are usually associated with numbers. The DNS server tries servers with lower numbers first, so your server's number should be lower than your ISP's.
    2 Open Mac OS Server Admin and log on to the server you want to administer.
    3 Press the Mail Services button and choose Show Host List.
    4 Double-click the ISP's mail server in the host list.
    If the ISP's mail server is not yet in the host list, click the New Host button and type the name of the server. Then double-click the name in the list.
    5 Click the Schedule tab.
    6 Make the changes you want to the Schedule settings.
    You must enable Remote Mail Polling (ETRN).
