What MailShelf Pro is
MailShelf Pro is a Windows application for secure, compliant, long-term email archiving deployed on premises. It creates tamper-proof one-to-one copies in a central archive and can archive any amount of data and any number of emails. Scheduled archiving and full-text search help organize and retrieve stored messages, with export to an email server or email client. Supported sources include Microsoft 365, Microsoft Exchange, Google Workspace, IMAP4, and POP3. It works with Outlook Classic, Thunderbird, SeaMonkey, and Postbox, and supports EML, MSG, PST, OST, DBX, and MBOX formats. Listed controls include retention rules, archiving of S/MIME- and PGP-encrypted email, individual user rights, activity logging, and audit capabilities. Spam can be excluded with SpamAssassin, DNSBL queries, and blacklists. Pricing starts at €39.99, with a 30-day unrestricted trial and no free plan. The permanent license remains usable after its one-year Update & Support Subscription ends, but updates and technical support stop unless renewed.
