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.

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.

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.
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.
