Domains, DNS, hosting and email from a single source.
Resources & Support



We write MX, SPF, DKIM and DMARC into your zone. You see every change before it happens.
Real mailboxes on your own domain. We write SPF, DKIM and DMARC into your zone with one click, so your mail lands in the inbox, not in spam.
Pro features as standard
Features from the running mail server, not from a wish list. Every one of them is usable today.
Every account gets its own storage. Your package allowance is yours to divide freely, so the mailbox that needs room gets it, with no rigid per-mailbox cap in the way.
Appointments and contacts over CalDAV and CardDAV, on iPhone, iPad, Mac, Thunderbird and Android. The event you create on your Mac is on your phone seconds later.
The reminder is triggered on our side and mailed to you. It reaches you with every device switched off.
Spam detection per mailbox, per domain and globally, with the origin of every rule in plain sight. You set the tag threshold yourself; the hard reject threshold comes with Business.
Every attachment is checked. Dangerous file types are rejected outright before they are ever delivered.
Blocked senders get the same answer as an unknown address. Spammers cannot tell a real mailbox from a dead one.
Server-side filter rules and auto reply. They keep working even when none of your devices is online.
A separate password per device, plus TOTP two-factor. Your main password stays protected and you revoke devices one by one.
IMAP import from any old mailbox. It runs in the background, can be resumed and shows you live progress.
The difference
If your domain points at regfish nameservers, we set up deliverability for you completely. No copying cryptic DNS records, no misplaced signature. With a preview of every change before it reaches the zone.
Exactly the reason to book with regfish instead of a US provider: domain, DNS and email from one source, tuned to each other.
Reachable everywhere
Open your mail in the browser or in your favourite app. Standard IMAP and SMTP over TLS. No proprietary protocol, no lock-in. On your laptop, phone and tablet, always in sync.
See the webmailWhat never arrives
Spam detection, virus scanning and greylisting run on every mailbox. Beyond that you can step in yourself, as precisely as you want.
Single addresses or whole domains with patterns like *@spam.example. On every plan, right inside the mailbox.
Blocked senders get the same answer as an address that never existed. They never learn that your mailbox is there.
Rules globally, per domain and per mailbox. Every setting shows which level it came from, so you never have to guess.
A banner spells out SPF, DKIM, DMARC, the spam score and the virus scan. External images load only when you ask for them.
More than mailboxes
Every mailbox comes with a calendar and an address book. Both reach every device you own over CalDAV and CardDAV, with no app to install and nothing extra to pay.
Reminders are triggered on our server and mailed to you. They reach you with every device switched off, and they cover events you created in Apple Calendar.
Add the sender of any message to your address book with one click. While you write, the mailbox suggests recipients from your contacts and your history. Change the same contact on your phone and in the browser at once and you get a warning instead of a silent overwrite.
Enter it once
Open standards, no app of ours. Your mailbox, your appointments and your contacts run over IMAP, SMTP, CalDAV and CardDAV, so with the program you already use. A new phone pulls everything back in minutes.
The exact settings and addresses are waiting in your customer area after you book, ready to copy, with a guide for each program.
Sign in with your mailbox credentials. You can also issue a separate app password for each device and revoke them one at a time.
Migration
No support ticket, no waiting: you do it yourself and we take the fiddly parts off your hands.
No risk
If it does not suit you, send us an email within 30 days and you get the price of the package back. No reason needed, no questions asked. This applies to business customers too, who have no statutory right of withdrawal.
Details in the supplementary terms, § D4We do not impose an hourly cap on you. Our acceptable use policy applies, so fair use rather than a counter.
Read the acceptable use policyWe do not read your mail, we insert nothing and we sell nothing on. The mailbox is the product, not you.
Your basket holds what you put in it. When you change plan we credit the remaining term against the new one.
Live chat and email, answered by the same people who run the service. Usually within minutes, not working days.
