How e-mail is protected
The foundation is correct DNS and sender authentication: SPF, DKIM and DMARC. Anti-spam, reputation, antivirus and heuristic filters add further layers.
Custom malware lists and signatures are updated regularly, and suspicious messages can go to SpamBox instead of mixing with the inbox.
Spoofing and phishing
Spoofing means impersonating a sender, domain or organization. It often abuses DNS mistakes, similar domains or a missing enforced DMARC policy.
MSFE, SPF, DKIM, DMARC, domain reputation and incident handling reduce risk, but domain-side configuration still matters.
E-mail, website and DNS
E-mail depends on the domain, DNS and reputation. During migration, MX, SPF, DKIM, DMARC, certificates, ports and mail clients should be tested.

Are SPF, DKIM and DMARC required?
They are strongly recommended for business e-mail because they help recipient servers verify whether a message really comes from the domain.
How is spam different from phishing?
Spam is unwanted mail, while phishing attempts to steal data or impersonate a trusted party. A message can be both spam and phishing.
What does SpamBox provide?
SpamBox separates suspicious messages from the inbox and lets users control retained mail through daily reports.
Can delivery to the recipient server be confirmed?
Yes, the SMTP trail can show that the recipient server accepted a message, even if the final user does not see it.
