Managing email efficiently is essential for both personal and professional communication. PlusNet, a popular UK-based Internet Service Provider, offers a webmail service that supports IMAP (Internet Message Access Protocol), allowing users to sync their email across multiple devices. This guide walks through the correct IMAP settings for PlusNet Webmail and explores reliable methods to back up your messages.
PlusNet Webmail is a UK-based email service that lets users read, send, receive, and manage messages from any browser or through email clients like Outlook, Thunderbird, or Apple Mail. Supporting both IMAP and POP—while recommending IMAP for seamless real-time syncing—it offers a straightforward platform for convenient, cross-device email access.
Quick Solution: – Secure your important emails today. Back up your PlusNet Webmail account to prevent data loss and free up space. Download the Shoviv IMAP Backup and Restore tool and get a local copy of your important emails.

IMAP (Internet Message Access Protocol) enables you to manage your mailbox from multiple devices without downloading everything locally. All changes you make—like reading, moving, or deleting messages—reflect instantly on the server and other connected devices.
Understanding IMAP vs. POP3
Before diving into the configuration, it helps to understand why IMAP is the preferred protocol:
- IMAP stores messages on the server, ensuring that changes made on one device (such as reading, deleting, or organizing emails) are reflected everywhere.
- POP3, in contrast, typically downloads and removes messages from the server, which can lead to data loss or fragmented mailboxes if you switch between devices.
IMAP provides seamless synchronization for users who access email from a laptop, smartphone, and web interface.

Typical PlusNet IMAP configuration:
To set up PlusNet email in clients such as Outlook, Thunderbird, Apple Mail, or mobile apps, use these key parameters:
| Setting | Value |
|---|---|
| Incoming Mail (IMAP) Server: IMAP Port Number (SSL/TLS enabled): | imap.plus.net / relay.plus.net 993 or 143 |
| Incoming Mail (POP3) Server: POP3 Port Number (SSL/TLs enabled): | ppp3.plus.net / relay.plus.net 995 or 110 |
| Outgoing Mail (SMTP) Server: SMTP Port Number (SSL/TLS enabled): | smtp.plus.net / relay.plus.net 587/25 or 465 |
| Authentication Encryption | Full PlusNet email address & password SSL/TLS |
Why do you need to take a Backup?
Even when emails are stored on the server through IMAP, unexpected issues can lead to permanent data loss. Creating regular backups safeguards critical messages and ensures uninterrupted access in any situation.
- Server Outage or Mailbox Corruption – Hosting servers can fail or become corrupted without warning, making your messages temporarily or permanently inaccessible.
- Accidental Deletion – Whether through user error or automated cleanup, important emails can be removed and may not be recoverable.
- Service Changes or Migration – Moving to another email provider or changes in your ISP account—such as cancellation or upgrades—can disrupt access to stored emails.
- Cybersecurity Threats – Hacking attempts, ransomware, and other cyberattacks can compromise or encrypt your mailbox, putting valuable communication at risk. Backup always favours the users.
- Regulatory and Compliance Needs – Businesses and professionals often need long-term archives to meet legal, financial, or industry record-keeping requirements.
In short, a proactive backup strategy ensures your email history remains secure, accessible, and entirely under your control, no matter what challenges arise.
All Dimensions for Backing Up PlusNet Webmail
Even with IMAP, backing up your mail box is critical for disaster recovery or when you plan to migrate to another provider.
1. Email Client Export
- Connect your PlusNet account to an email client such as Mozilla Thunderbird or Microsoft Outlook.
- Once fully synchronized, use the client’s Export or Archive feature to create a local copy (e.g., MBOX or PST files).
- Stores these files on an external drive or cloud storage.
2. Manual Webmail Download
- Log in to PlusNet Webmail.
- Select messages or folders and use the ‘Download’ or ‘Save As’ options (availability depends on the webmail interface version).
- This method works best for small mailboxes or selective backups.
3. Migration to Another Service
- Suppose you’re moving to Gmail, Outlook.com, or another provider. In that case, you can add your PlusNet account to the New service and let it import all messages via IMAP.
Best Practice for Secure Email Management
- Use strong, unique passwords and enable two-factor authentication wherever possible.
- Verify storage limits to prevent bounce-backs when your mailbox nears capacity.
- Test backups periodically by restoring a sample message to confirm integrity.
