 On low-bandwidth networks, it can be useful to limit the amount of messages downloaded in each sync. The default is 8. Set to 0 to download all available messages every time a sync occurs.

+You can specify a required stamp cost for inbound messages to be accepted. Specifying a stamp cost will require untrusted senders that message you to include a cryptographic stamp in their messages. Performing this operation takes the sender an amount of time proportional to the stamp cost. As a rough estimate, a stamp cost of 8 will take less than a second to compute, and a stamp cost of 20 could take several minutes, even on a fast computer.
