The Email Account area in the Windows control panel provides a comprehensive set of options for configuring individual mailboxes. Understanding each setting is crucial for maintaining proper email flow, security, and user experience. This guide explains all available options one by one, adding context on why they matter, recommended usage, and potential issues.

You should have domain-level access to the control panel to modify these settings. Always consider the role of the mailbox before changing options—for example, a customer support address may need different settings than a personal one. Incorrect settings can cause emails to bounce, prevent logins, or allow unwanted access. Review the options below to configure your accounts effectively.

#Mailbox Size, Status, and Encoding

Mailbox Size Limit (in MB) - The maximum size of the mailbox (in MB). This is the total amount of email and attachments that the mailbox can store on our servers. When this limit is exceeded, the server will reject new messages, sending a bounce notification to the sender. To determine an appropriate limit, assess the user's email habits and expected volume of attachments. Heavy users should start with at least 500 MB. Regularly check mailbox usage in the control panel to avoid unexpected disruptions. This limit applies server-side only and does not impact emails already downloaded to a local client via POP3 or IMAP.

Account Status - The status of the mailbox account. Enabled - The mailbox is fully active and available. Disabled - The mailbox is fully disabled and cannot send or receive mail and may not login to the webmail interface. Incoming email is rejected or bounced. Disabled With Mail - The mailbox is disabled and cannot send or receive mail and may not login to the webmail interface. Incoming email is accepted and stored. Use Disabled With Mail when suspending access but retaining messages for later administrative review or compliance purposes. Changes here take effect immediately.

Text Encoding - The encoding method used for outgoing emails sent through the webmail interface. We recommend leaving this option at UTF-8. UTF-8 supports virtually all characters from every language, preventing issues with accented letters or special symbols that can appear garbled under older encodings. Only change this if you have a specific compatibility requirement with legacy systems, as incorrect encoding can cause messages to display incorrectly for recipients.

#Permissions, Security, and Service Access

Domain Administrator - The mailbox account has "Domain Administrator" permissions and privileges to the associated email domain. Grant this only to trusted users who require the ability to manage other accounts and domain-level settings. Lock Password - The password cannot be changed through the webmail interface and can only be changed through the control panel. This is essential in managed or corporate environments to maintain centralized control. Hide From Global Account List - When composing an email through the webmail interface, the user is given a list of email accounts on the same domain; enabling this prohibits the mailbox from being listed. Useful for administrative or system accounts that should not appear as selectable sender addresses.

Enable Greylisting - Greylisting is an anti-spam technology that temporarily rejects email that is suspected of being spam. The server returns a temporary 4xx error, forcing the sending server to retry after a delay. Legitimate mail servers almost always retry successfully; spam sources frequently do not. This can delay first-time legitimate senders by 5-60 minutes. This setting should only be disabled if required (such as a sales or support mailbox) because timely delivery is business-critical. Common pitfall: disabling globally instead of per-mailbox, which weakens overall spam protection. Monitor logs for persistent retry failures from known good senders and consider whitelisting.

Service Access - The allowed services for the mailbox account. Enable only what the user actually needs to follow the principle of least privilege and reduce the attack surface if credentials are ever compromised. The options and their effects are: - POP3: Allows POP3 access from a POP3 client (such as Outlook) - IMAP: Allows IMAP access from an IMAP client (such as Outlook) - Incoming SMTP: Allows incoming emails to be received and processed - Outgoing SMTP: Allows outgoing emails to be sent and processed - WebMail: Allows access to the Webmail interface - XMPP (Chat): Allows access to the XMPP (chat) service and services

This message may contain confidential information and is intended only for the named recipient.

First Name - The first name of the mailbox account. Last Name - The last name of the mailbox account. These populate the display name in email headers and webmail. Reply To Address - The address used when an email is sent through the webmail interface. This address is used when a recipient replies to an email sent from the mailbox. It can differ from the sending address for support or noreply workflows. Signature - The signature that is added to all emails sent through the webmail interface. Keep signatures under 500 characters, include necessary legal disclaimers if required, and avoid large images that trigger spam filters. Backup Address - Is used if a password reset request is sent through the webmail interface; this account is used to send the reset password confirmation. Verify this address is actively monitored.

Enable Auto-responder - Enables the use and sending of auto-responders. Ideal for out-of-office notices or order confirmations. Auto-responder Subject - The email subject used when sending an auto-response; keep it concise and descriptive so recipients immediately understand it is automated. Auto-responder Message - The email message used when sending an auto-response. Include return dates, alternate contacts, or expected response times. Test thoroughly because the responder will reply to every incoming message, including spam. Avoid embedding sensitive data.

Forward Mail to Address - Any incoming email is forwarded to this address. This is commonly used to consolidate mail from several mailboxes into a single daily inbox or to route mail to an external processor. Delete Message on Forward - If enabled, when an email is forwarded the email will be deleted from the mailbox account on successful forwarding. Disable this if you must retain a server-side copy for auditing, backup, or legal retention policies. Forwarding loops are a common pitfall; ensure the destination address does not forward back to the original mailbox.

Proper configuration of these options ensures your email accounts function as intended. Start with enabling only required services, sensible storage limits, and greylisting for most accounts. If you encounter delivery or access problems, first verify account status, service access flags, and size limits. For further setup steps such as connecting desktop clients or domain-wide email routing, consult the control panel help sections or contact our support department.
