Description:
simple email archiver written in perl
Archmbox is a simple email archiver written in perl; it parses one or more mailboxes, selects some or all messages and then performs specific actions on the selected messages. At this time archmbox supports mbox and mbx mailbox formats. . Messages selection is based upon a date criteria; an absolute date or a days offset can be specified. It is also possible to refine the selection using regular expressions on the header fields of the message. All archived messages are stored in a new mailbox with the same name of the original one plus .archived as extension (this is the default, but can be changed); the archive mailbox can be saved in gz or bz2 compressed format as well.
