Create and manage email accounts for any domain hosted on your server:

  • Account creation — [email protected] with password and quota

Autoresponders​

Configure automatic replies using Dovecot Sieve:

  • Custom subject and message body
  • Start/end date scheduling

  • Roundcube — Modern webmail interface

Email Authentication (DNS)​

Panelica automatically manages email authentication DNS records:

  • DKIM — 2048-bit RSA signing (sha256), auto-generated keys per domain
  • DMARC — Policy enforcement (quarantine/reject) with reporting
  • MX Records — Automatic MX record creation pointing to mail server
  • PTR Record — Reverse DNS guidance for deliverability

Cloudflare Mail DNS Sync​

For domains using Cloudflare DNS, Panelica can sync all 6 mail-related records in one click:

  1. MX record (priority 10)
  2. Mail A record (proxy off)
  3. SPF TXT record (root domain)
  4. SPF TXT record (mail subdomain)
  5. DKIM TXT record
  6. DMARC TXT record

Mailing Lists​

Create and manage mailing lists for bulk communication:

  • Subscriber management (add/remove)
  • Custom list addresses
  • Moderation options

Access Control (RBAC)​
