If you will be communicating with other Snap Mail users over a slow-speed link, for example using AppleTalk Remote Access software, then you must set these preferences to indicate the slowest speed you will be using to communicate over the link. These preferences must be set for both the remote Mac and any Macs on the network that will be communicating directly with the remote Mac. Usually remote Macs will be set to send all their mail directly to a server, so you’ll only need to set this preference on the server Mac.
• Slow-Speed Modem Link in Use
When this preference is checked, Snap Mail changes important timing information to handle communicating over a slow link. If you have checked this preference, make sure to select the slowest speed at which data will be transmitted over the link. For example, you may have a network modem that can handle up to 9600 baud, but some users may connect to it at slower speeds.
If the link is subject to interference, for example if it is an international phone line, make sure to check the “Link is Noisy” preference.
In some cases where lines are very noisy it is helpful to drop down to a slower modem-speed setting. This does not actually slow the baud rate down; it just tells Snap Mail to be more patient while waiting for responses from a remote machine.
