<p num="1"><br/><br/><br/>An e-mail processing system that preferably operates solely within <br/>nonpersistent storage such as random access memory. Queues of e-mails are <br/>formed within the random access memory, where each queue includes a pointer to <br/>personalized information about the e-mail, directed to a specific domain. In <br/>order to send the e-mail, a channel is opened to the domain, and while open, e-<br/>mails within the queue are sent. A special recovery agent periodically takes <br/>snapshots of the state of processing within the system. Since the processing <br/>is occurring within nonpersistent storage, a failure within the system can be <br/>recovered by using the snapshots to recover where each e-mail is processing. <br/>In one aspect, the feed rate to the other e-mail servers is adjusted based on <br/>the rate of those e-mail servers. Also, the system asynchronously looks up <br/>information such as DNS information while it is processing information for <br/>other e-mails.<br/> |
