Changing server network settings

    You can change how your Mail Server manages its network connections and processes DNS requests.

    To change the server's network settings, follow these steps:
    1 Log on to AppleShare IP Remote Admin.
    2 Make sure the Mail Server is running.
    3

    Click the Mail server button.


       
    4 Click the Server Settings button.
    5 Click Advanced Server Options.
    6 Click Network.
    7 Click the Cache DNS or "Always check DNS" button.
    If you click Cache DNS, your server stores DNS results. When your server sends mail, it verifies the domain names in the outgoing mail address by contacting your network's DNS server to find IP addresses for the addressed domains. Since the DNS database doesn't change very frequently, a cache of DNS results can improve performance.
    If you click "Always check DNS," your server polls the DNS server every time it connects. This option is more reliable because cached DNS information might be out of date. For more information, see The Mail Server and DNS.
    8 If you chose Cache DNS, choose the length of time you'd like the results to be cached.
    Click "Respect 'Time to Live' (TTL) DNS Settings" if you prefer to use the DNS server's recommended TTL time.
    Click "Cache DNS information for <n> minutes," then enter a number of minutes, if you prefer to specify a length of time for the DNS information to be cached.
    9 Choose the information the Mail Server will request from the DNS server. Be sure to click a button directly under the network DNS choice you made in step 7.
    10 To set how long the Mail Server should try to establish a network connection to another mail server host, type a number in the "Open connection <n> seconds" box in the Timeout section.
    100-120 seconds is considered adequate. You may want to change this if you're contacting a host that typically takes longer to respond.
    11 To set how long the Mail Server should wait for a response when the connection is open, type a number in the "Read/write <n> seconds" box in the Timeout section.
    100-120 seconds is considered adequate.
    12 Click the Save button.
