Mailboxes, clients, forwarding and deliverability.
Creating mailboxes on your domain, connecting them to Outlook, Apple Mail, Gmail or a phone, and — the part most guides skip — making sure what you send actually arrives. Deliverability is mostly DNS: SPF, DKIM and DMARC records that prove your mail is really yours. Those are covered here too.
How to open and use the browser-based inbox that comes with every mailbox, without installing a mail app.
IMAP or POP3: which should you choose?The difference between the two ways an email app can fetch your mail, and why IMAP is the right default for almost everyone now.
SPF, DKIM and DMARC explainedThree DNS records that between them answer one question: is this message really from you? Here is what each proves.
What are MX records?What an MX record does, why it is separate from your website's DNS, and where to find the ones set for your domain.
What is email spoofing, and can you prevent it?How a spoofed email fakes its sender address, why it is possible at all, and the records that make it harder to pull off.
What is a mailbox quota and what happens when it is full?What a mailbox quota is, what happens the moment a mailbox reaches it, and how to free up space again.
What to do if your domain is blacklistedHow to check whether your domain has been blacklisted, what typically causes it, and how to get it removed.
Which email ports should I use?Every port number a mail client asks for, what each one is used for, and which ones to actually choose.
Why your emails go to spam, and how to stop itEvery common reason outgoing mail is filtered as spam, ordered from the fixes that matter most to the ones that matter least.
