Managing on-demand email storage
View Patent ↗A method, system, and program for managing on-demand email storage are provided. An email service provider allocates a predetermined amount of storage space to an intended recipient. When an email is received for the intended recipient at the email service provider, the email service provider determines whether the predetermined storage space has sufficient capacity for storage of the email. If the predetermined storage space is insufficient for storage of the email, then the email service provider allocates on-demand storage space to the intended recipient. The email service provider then stores the email in the on-demand storage space, such that the email is stored, rather than discarded, when the predetermined storage space reaches full capacity. Before allocating on-demand storage space, the email service provider may compare the email characteristics with predefined criteria set by the intended recipient for emails to be stored in on-demand storage space.
1. A method in a computer system for managing on-demand email storage, comprising:
receiving an email for an intended recipient at an email service provider, wherein a predetermined storage space of a specified size is allocated to said intended recipient by said email service provider;
determining whether said predetermined storage space has sufficient capacity for storage of said email;
responsive to determining said predetermined storage space has insufficient capacity for storage of said email, determining whether said email matches with criteria set by said intended recipient specifying a domain name in a sender address for addition of said on-demand storage space
responsive to a particular sender address in said email matching said domain name in said sender address specified in said criteria, allocating by said email service provider on-demand storage space to a total storage space allocated to said intended recipient comprising said predetermined storage space and said on-demand storage space and storing said email in said allocated on-demand storage space, such that said email is stored, rather than discarded, when said predetermined storage space reaches full capacity; and
responsive to said particular sender address in said email not matching said domain name in said sender address specified in said criteria, discarding said email.
2. The method according to claim 1 for managing on-demand email storage, wherein allocating by said email service provider on-demand storage space to a total storage space allocated to said intended recipient comprising said predetermined storage space and said on-demand storage space further comprises:
determining, responsive to determining said predetermined storage space has insufficient capacity for storage of said email, whether said intended recipient is registered for said on-demand storage space;
responsive to determining said intended recipient is registered for said on-demand storage space, allocating on-demand storage space to said intended recipient; and
responsive to determining said intended recipient is not registered for said on-demand storage space, discarding said email.
3. The method is according to claim 1 for managing on-demand email storage, wherein said criteria comprises at least one from among an email identifier, an email size, and a keyword.
4. The method according to claim 1 for managing on-demand email storage, further comprising:
charging said intended recipient for said allocated on-demand storage space.
