Questions about Email Security
Is Backup MX included in Email Security?
Yes. Email Security includes Backup MX continuity, so you do not need to buy it separately for the same domain.
Can a rule switch off the antivirus scan?
No. Trusted sender rules can relax spam decisions, but every message is always scanned for malware.
Which mail does Email Security protect?
Incoming mail for your domain. Outgoing mail from your own servers is covered by the SMTP Relay add-on.
How much does it cost?
USD 45 per domain per month, taxes included, with no long contract.
