Short answer: Sign in at webmail.infosaic.com with your administrative email address, then go to Settings (the gears icon) → Domain Settings → Users → Add New. The mailbox works the moment you save it.
Applies to: Infosaic web hosting · adding and managing mailboxes
Shortly after signing up you are given one administrative email address and password. That account is the one that can create every other mailbox on your domain, so it is worth knowing where it lives and keeping it somewhere safe.
Everything to do with mailboxes — creating them, aliases, forwarding — happens in webmail rather than in the hosting control panel. That catches people out, because the control panel is where almost everything else happens.
How to add a mailbox

- Go to webmail.infosaic.com.
- Sign in with your administrative email address — the full address, in the form [email protected] — and its password.
- Click the Settings icon, the pair of gears on the left.
- Under Domain Settings, click Users.
- Click Add New.
- Enter the username, a password and a display name. You do not type the domain — it is added for you, so enter sales rather than [email protected].
- If this person also needs to manage mailboxes, enable domain administrator access. Give that sparingly.
- Save. The mailbox can receive mail immediately.
A mailbox, an alias, or forwarding?

Three different things, and choosing the wrong one is why people end up with more mailboxes than they need.
- A mailbox is a real account with its own password and its own storage. Someone signs in to it.
- An alias is an extra address that drops into an existing mailbox. No password, no storage, no second inbox to check.
- Forwarding sends mail on to a different address entirely, inside or outside your domain.
For most small businesses that means one mailbox per person, plus aliases for info@, sales@ and support@ pointing at whoever handles them. When the person changes, you repoint the alias and nothing else moves.
Guard the administrative account. It can create, change and delete every mailbox on your domain. Give it a long unique password, and do not hand out domain administrator access to people who only need to read their own mail.
After you create the mailbox
Two things usually follow:
- Test it in webmail first. Sign in as the new user and send yourself a message. If webmail works, the mailbox is correct and anything that goes wrong afterwards is a client setting.
- Set it up on a computer or phone using mail.infosaic.com — see configuring email on your device.
Questions and answers
How do I create a new email address on my domain?
Sign in to webmail.infosaic.com as the administrator, open Settings, then Domain Settings, then Users, and click Add New.
Where do I manage mailboxes — webmail or the control panel?
Webmail. The hosting control panel handles the website and the account; mailboxes are created in webmail.
Do I include the domain in the username?
No. Enter just the part before the @, such as sales. The domain is added for you.
What is the administrative email address?
The account you were given when the hosting was set up. It is the only one that can create and manage other mailboxes, so keep it safe.
Should I create a mailbox or an alias?
An alias if the mail should land in someone existing inbox, which covers most shared addresses. A mailbox only when it genuinely needs its own login and storage.
How many mailboxes can I have?
That depends on your hosting package. If you are near the limit or need more, open a support ticket.
Can I give someone else permission to manage mailboxes?
Yes, by enabling domain administrator access on their user. Do it sparingly, because it grants control over every mailbox on the domain.
The mailbox exists but mail will not send from Outlook.
That is a client setting rather than the mailbox. Check the username is the full email address and that outgoing authentication is switched on.

Still stuck?
Open a support ticket from your hosting control panel at controlpanel.infosaic.com — that is the fastest route, because it reaches the team who can already see your account. You can also email [email protected].
