Abstract: A system provisions an electronic mail (email) account of a user for allowing access to an electronic mailbox from a remote device to retrieve email. A communications module receives email address parameters of the user and transmits a domain name system (DNS) query to the Internet for returning mail exchange (MX) records corresponding to the email address parameters of the user. A configuration module processes any returned MX records as a starting point for determining configuration parameters for accessing the email account of the user to retrieve user email.

Abstract: A communications system may include a plurality of target servers and a plurality of source servers connected to the Internet via respective different portions thereof. The source servers may be for establishing connections to desired target servers via the Internet, and they may also be subject to connectivity disruptions. Further, the source servers may generate connectivity disruption information for respective target servers. The communications system may further include a dispatcher for collecting the connectivity disruption information from the source servers, and for distributing jobs to the source servers based upon a respective target server associated with each job and the connectivity disruption information for the respective target server.

Abstract: A communications system may include a plurality of source message servers for storing messages for delivery to a user, a target message server having a target message box associated therewith, and an aggregation server for periodically aggregating the messages from the source message servers to the target message box for retrieval by the user. The target message server may provide a delivery failure message to the aggregation server based upon a failure to deliver a message to the target message box. As such, the aggregation server may increase a period of sending messages to the target message box based upon a delivery failure message therefrom, and thereafter decrease the period of sending messages to the target message box based upon a successful delivery of a message thereto.

Abstract: A communications system may include an application server and at least one communications device for processing requests from one another. The communications device may process requests using an HTTP client application, for example. Furthermore, the system may also include an HTTP server for interfacing the HTTP client application with the application server. The HTTP server and the HTTP client application may format requests to be communicated therebetween via the Internet in an HTTP format, and each may provide additional state information with the HTTP formatted requests recognizable by the other for authenticating the application server and the HTTP client application to one another. Furthermore, the HTTP client application may request a first universal resource locator (URL) from the HTTP server for accepting work requests from the application server, and a second URL different from the first URL for responding to work requests from the application server.

Abstract: A system for provisioning an electronic mail (email) account of a user for allowing access to an electronic mailbox from a remote device to retrieve email includes a communications module that receives email address parameters entered by the user and transmits a domain name system (DNS) query to the Internet for returning mail exchange (MX) and address (A) records corresponding to the entered email address parameters of the user. A configuration module processes any returned MX and A records to determine whether the email address parameters entered by the user are valid before attempting to provision the email account of the user.
