BitterHost

Email that actually belongs to your domain

Stop handing your domain identity to free inboxes. Run your own domain mailboxes with BitterHost and ISPConfig.

Domain mailboxes with control

Each BitterHost plan includes mailboxes tied to your domain. You can create user mailboxes, aliases, catch all addresses, and mailing lists from your ISPConfig panel.

  • IMAP and SMTP for desktop and mobile clients
  • Modern webmail interface at mail.bitterhost.com
  • Forwarders, aliases, and vacation autoresponders
  • Server side filters and spam controls

Deliverability matters

Mail deliverability is a shared responsibility. We take care of server side configuration, but you also need healthy sender practices and DNS records.

Server side

  • SPF, DKIM, and DMARC templates
  • Reverse DNS set for mail hosts
  • Shared or dedicated outbound IPs depending on plan
  • Reasonable rate limits to protect reputation

Your part

  • Clean subscriber lists and opt in practices
  • Templates that look like humans wrote them
  • Reasonable sending volumes per day
  • Timely replies to abuse reports
