Company-domain email that mail providers trust

An address like name@company.rs is not only about how a signature looks. It also decides whether your mail reaches the customer — and whether someone can send mail pretending to be you.

  2. SPF checkThe recipient checks whether this server may send on the domain's behalf
  3. Signature checkDKIM confirms the message was not altered in transit and really comes from you
  4. DMARC policyThe domain declares what to do with mail that fails, and receives reports on spoofing
  5. ReputationThe domain's history counts: complaints, bounces and recent sending volume
  6. Into the inboxThe message lands in the inbox rather than spam, and the customer sees it the same day

WHAT IS USUALLY WRONG

Signs it is time to sort the mail out

As it stands

  • Staff write to customers from personal addresses on free services
  • The company's mail regularly lands in spam and nobody knows why
  • Customers receive “mail from your company” that you never sent
  • An employee left — and the correspondence with their customers left with the mailbox
  • Three people read office@ and nobody is sure whether anyone replied

How it should be

  • All correspondence runs on the company domain with consistent addresses and signatures
  • The domain is signed and declared: mail services recognise the message as genuine
  • A DMARC policy stops others sending in your name from foreign servers
  • The mailbox belongs to the company: when someone leaves, the correspondence stays
  • Shared addresses work as groups with clear responsibility for replying
WHAT THE WORK INCLUDES

What the email setup covers

Audit of the current state

Where the mail lives now, which domain records exist and whether spoofing has been attempted.

Mailboxes and groups

Personal addresses and shared department addresses with access and forwarding rules.

Domain records

SPF, DKIM and DMARC are configured together rather than one at a time — otherwise the checks disagree.

Mail migration

Message history, folders and contacts move from the old service without downtime.

Protection

Antispam, attachment filtering, two-factor sign-in and protection against password guessing.

System mail

A separate channel for the site's mail: enquiries, confirmations and alerts stay out of the way.

Device setup

Mail on staff phones and computers, with consistent company signatures.

Watch after launch

DMARC reports and blocklist checks — so a problem is spotted before customers complain.

TECHNOLOGY LANDSCAPE

What the mail setup is made of

SMTP · IMAPSending and mailbox access from any device
SPF · DKIM · DMARCThree checks that together prove a message is genuine
AntispamFiltering incoming mail and quarantining suspicious attachments
TLSEncrypted connections for sending and receiving
BackupsMailbox copies away from the main server, verified by restore
DMARC reportsWho tried to send in your domain's name, and from where

The domain stays registered to your company and the mailboxes belong to it. We receive access for setup and support — and you can revoke it without losing the mail.

QUESTIONS

What people usually ask

Our mail goes to spam. Can that be fixed?

Usually yes, and it starts with the domain: DKIM signing, the SPF record and the DMARC policy have to agree with each other. Then we look at reputation: whether the server landed on blocklists from past sending and whether complaints exist. A one-off fix without watching the reports tends to hold only briefly.

Someone is sending mail in our name. What now?

A DMARC policy handles it: the domain declares that mail without a valid signature should be rejected. The policy starts in a soft mode while reports are collected — they show who sends and from where, including your own forgotten services. Then the mode is tightened and the forgeries stop arriving.

Can mail be migrated without downtime?

Yes. First we copy the message history to the new server while the old one keeps running. Then we switch delivery and sync the messages that arrived during the move. Staff keep working; the only change they notice is the new setup on their devices.

Our own server or a cloud service?

It depends on headcount and data requirements. A cloud service is simpler and more predictable to maintain; your own server gives full control and costs less at a large number of mailboxes. We say which is better in your case and set up either — there is no point pushing one.

What happens to a departed employee's mail?

The mailbox belongs to the company, so access passes to a manager or successor and incoming mail is forwarded to an active address. Customers keep writing to the address they know and still get answers — and the correspondence history stays with the company.
