FAQs IKARUS mail.security S/MIME-Feature

IKARUS mail.security

  • Is the S/MIME feature also available for stand-alone purchase (without IKARUS mail.security)?

    S/MIME it serves as an add-on to IKARUS mail.security and can therefore not be purchased separately.

  • What are the requirements for using S/MIME?

    S/MIME certificates can only be requested for domains whose MX record points to mx.mymailwall.com and which are set up in an inbound route.

  • Can internal e-mails also be provided with a certificate?

    Only e-mails sent via IKARUS mail.security/mymailwall are provided with an S/MIME certificate.

  • How can I provide mailboxes with a certificate?

    Under the menu item mail.security > S/MIME you will find a list of your mailboxes. Here you can activate one, several or all mailboxes. Signing then takes place automatically when the e-mails are sent via IKARUS mail.security/mymailwall.

  • Why don’t I see my mailbox in the S/MIME overview?

    Mailboxes must be entered in an incoming route as a known mailbox. Mailboxes entered in a wildcard route are not displayed.

  • Is the licence cross-domain or do I have to be purchase a llcence per domain?

    Analogous to IKARUS mail.security, the licence is purchased across domains and can therefore be used for any number of domains.

  • My licence number is displayed incorrectly on the IKARUS Portal. How can I change this?

    Please contact your responsible IKARUS Sales representative.

  • How can I encrypt emails?

    Currently, e-mails can only be signed. Encryption will be possible in the future, but there is no release date for this yet.

  • Where can I download the S/MIME certificate?

    Downloading S/MIME certificates is not technically provided for security reasons.

  • Can I also use an existing (third-party) certificate for certain mailboxes?

    You can upload as many existing (third-party) certificates as you wish within the scope of your existing licence, which will then be managed and used like IKARUS S/MIME certificates. Please note that these also count as licences and thus reduce your available quota.

  • What does the status "Revoke pending" ("in Deaktivierung" in Geman) mean?

    These are mailboxes that have been deactivated. This status remains up to 14 days until the status changes to “Inactive” (“Inaktiv” in German) and the licence becomes free again.

  • Does the S/MIME licence have to correspond to the IKARUS mail.security licence?

    No. The S/MIME licence can be less than or equal to the IKARUS mail.security licence.

  • How long is an S/MIME certificate valid?

    IKARUS S/MIME licences automatically receive the same validity period as your existing IKARUS mail.security licence. Technically, these are 1-year certificates, but they are automatically renewed at no extra cost (within the scope of the existing licence).

  • Is the S/MIME certificate recognised?

    The certificates are issued by Certum, a recognised certification authority.
