Professional email address
on your own domain name

Why use a professional email address?

A professional email address uses your own domain name (for example contact@your-company.com) instead of a free address. It:

• reassures your customers and strengthens your brand’s credibility;
• stays yours if you change internet service provider;
• lets you create one address per employee or per department (sales, accounts, support…);
• improves the deliverability of your messages, thanks to your domain’s SPF and DKIM signatures.

Which email plan should you choose?

The Pro and Expert plans cost the same whatever the number of mailboxes: you split the total space between a few large mailboxes or many small ones. Most of a mailbox’s space is taken up by attachments: if you exchange a lot of files, choose mailboxes of 10 GB or more.

What is included with every mailbox

• a webmail (Roundcube) available from any browser at webmail.yourdomain.com, which can be secured with HTTPS using Let’s Encrypt;
• IMAP, POP and SMTP encrypted with SSL/TLS, for Outlook, Thunderbird, Apple Mail and smartphones;
• automatic configuration of Outlook, Thunderbird and Apple Mail: your address and password are all you need;
• a spam filter adjustable for each mailbox, with allow and block lists;
• aliases, forwarding and automatic replies (out-of-office messages);
• DKIM signing and an SPF record to authenticate your outgoing mail;
• management of your addresses (creation, password, deletion) from the Plesk control panel;
• technical support by ticket 7 days a week from your customer area.

Setting up your email: IMAP, POP and SMTP

Your username is always your full email address. The server to use is the host name of the server that hosts your email (in the form srvXX.haisoft.net), given in your service activation message: it carries the certificate that secures the connection.

IMAP or POP? IMAP keeps your mailbox synchronised in real time between the server, your computer and your smartphone: a message read or filed on one device is read or filed on all of them. POP downloads messages to one computer and can delete them from the server to save space, at the risk of losing them if the computer is replaced. Choose the protocol when you set up the account: it cannot be changed afterwards without recreating the account.

Security and deliverability: SPF, DKIM and DMARC

For your emails to land in your recipients’ inbox rather than their spam folder, your domain must prove that your messages really come from you:

• SPF lists the servers allowed to send email for your domain. HaiSoft’s default record is v=spf1 a mx include:spf.haisoft.net -all;
• DKIM signs every outgoing email; signing is enabled in one click in Plesk, and the DNS record is created automatically;
• DMARC tells recipients what to do with a message that fails the SPF or DKIM checks;
• our servers present a correct name (HELO) and reverse DNS, and reject incoming emails that lack them.

Emails sent from HaiSoft shared servers are relayed through MailChannels, which filters outgoing spam and protects the reputation of the sending IP addresses: see email deliverability. Gmail and Yahoo require these standards from senders: read Gmail and Yahoo’s deliverability rules.

Protection against spam and phishing

Every mailbox has a content-analysis spam filter, which you enable and adjust in Plesk: the action to apply (moving spam to a dedicated folder is recommended), the filter sensitivity, and senders that are always accepted or always rejected. The Mail Pro and Mail Expert plans also include MailChannels Inbound advanced anti-spam, which blocks spam, viruses and phishing attempts before they reach your mailboxes.

A few good habits also reduce the spam you receive: do not publish your address in plain text on your website (use a form protected by a captcha instead), avoid overly generic addresses such as contact@ or info@, and limit mail forwarding. To find out more: spotting email scams.

Sending emails from your website

Your website’s contact forms and order emails must be sent via authenticated SMTP, from an existing address on your domain; the PHP mail() function, which does not authenticate the sender, is disabled. Our article Setting up email sending via SMTP for your website explains the configuration.
