MxGuard Help — Settings

Settings

The settings page lets you change your password, configure daily digest emails, and customise spam-handling thresholds per domain.

Password

Change your password by entering the current one and a new one twice. Passwords are stored as argon2 hashes — even MxGuard administrators can't see them.

Daily digest

Choose how often you want a summary email of quarantined mail:

  • Off — no digest emails
  • Daily — one email at 7 a.m. covering the previous 24 hours
  • Weekly — one email Monday morning covering the previous week
  • Monthly — one email on the 1st of each month

The digest includes every quarantined message in your scope with a score, reason, and one-click links to release, mark as spam, or mark as ham — all without needing to log in (signed tokens, valid for 7 days).

Scope of the digest

  • If you're a customer-admin, you receive quarantines across all your company's domains
  • If you're a regular user, you only receive quarantines addressed to your own email

Spam handling per domain

By default, MxGuard rejects messages at or above 0.97 and quarantines those at or above 0.75. You can override per-domain if certain domains need different behaviour.

Tag mode

Some customers prefer borderline spam to be delivered (with [SPAM] prepended to the subject) rather than quarantined. Enable tag mode for a domain to opt in:

  • Tag mode off (default) — borderline spam goes to quarantine
  • Tag mode on — borderline spam (0.50–0.75) is delivered with [SPAM] subject prefix; messages over 0.75 still quarantine

Advanced thresholds

Click the Advanced thresholds ▾ expander to set specific score cutoffs per domain. Three values:

  • Reject ≥ — scores at or above this get a 5xx SMTP reject (default 0.97)
  • Quarantine ≥ — scores at or above this go to quarantine (default 0.75)
  • Tag ≥ — scores at or above this get [SPAM] subject tag (default 0.75, which means tag mode is off)

For tag mode to be active, the tag threshold must be lower than the quarantine threshold. Setting tag = quarantine disables tagging.

Tip: Setting the reject threshold below 0.85 will likely cause false-positive rejections. Setting the quarantine threshold below 0.50 will fill your queue with noise. The defaults work well for most customers.

When changes take effect

All settings changes apply within 60 seconds — that's the cache TTL on domain configuration in the scanner. You don't need to restart anything.
