Frequently asked questions
Do I need to move my mailboxes?
No. Your mailboxes stay in Microsoft 365, Google Workspace, Exchange, Zimbra, Carbonio or your own server. You change your MX record and set a delivery target.
How long does the setup take?
Adding a domain, verifying it and setting the delivery target take a few minutes in the portal. The MX change then takes effect as DNS caches expire.
What happens if my mail server goes down?
Messages wait in our queue for up to 14 days, are retried every 3 minutes and are delivered as soon as your server answers.
Can users manage their own quarantine?
Yes. Each user signs in to a personal quarantine portal in one of 8 languages. Your IT team decides which quarantine reasons users may release; malware is never released by a user.
Which languages does this website offer?
English, Turkish, Egyptian Arabic, Spanish, German and French. We pick a language from your location and you can change it at any time.
