What 4SecureMail is

4SecureMail provides secure email accounts and managed email hosting for businesses and consumers. Accounts work with standard email clients such as Outlook and Thunderbird through POP, IMAP and SMTP connections using SSL/TLS. Its SecureVault feature encrypts sensitive outgoing messages to outside recipients, who can read and reply through a secure web link. SpamAssassin filtering, a challenge/response whitelist and a server-based ICSA-certified virus scanner are included.

The service supports mobile IMAP IDLE notifications and connections from multiple devices. Outgoing messages can carry attachments totaling up to 5 GB across all recipients. The company describes support for HIPAA, GLB and SOX, can provide or review a Business Associate Agreement, and offers off-site legal archiving at additional cost. Mailbox plans range from one mailbox with 500 MB storage and no custom domain to options with multiple mailboxes and custom-domain support. There is no free plan, but a free trial is available. Prices listed include Personal Basic at $7.49 a month and other plans billed every three months. The service is available on Android, iOS, Linux, macOS, web and Windows.
