Connecting an Email Client to a Mailbox

How to Connect an Email Client to Your Mailbox (IMAP/POP3 + SMTP) #

Want to use your Hosticko email on Outlook, Thunderbird, Apple Mail, or a mobile mail app?
This guide shows you the exact IMAP/POP3 and SMTP settings you need to connect your mailbox and start sending/receiving emails.

Step 1: Gather the required information #

Before you start, make sure you have:

  • Email address (example: you@yourdomain.com)
  • Incoming server (usually mail.yourdomain.com)
  • Outgoing server (SMTP) (usually mail.yourdomain.com)
  • Username (usually your full email address)
  • Password (your mailbox password)

These are the core values every email client asks for. :contentReference[oaicite:2]{index=2}

Step 2: Open your email client #

Launch your preferred client such as Microsoft Outlook, Mozilla Thunderbird, Apple Mail, or a mobile mail app. :contentReference[oaicite:3]{index=3}

Step 3: Add a new email account #

  1. Find Add Account in your email client (often under Account Settings or Preferences).
  2. Start the setup process and choose Manual setup if your client asks.

Most clients try “auto-detect” first—manual setup gives you full control when auto-detect fails.

Step 4: Choose IMAP or POP3 #

  • IMAP: Syncs mail across devices (recommended for most users). :contentReference[oaicite:4]{index=4}
  • POP3: Downloads emails to one device (older setup style). :contentReference[oaicite:5]{index=5}

Step 5: Enter your account settings #

  1. Your name: the display name recipients will see.
  2. Email address: your full email address.
  3. Password: your mailbox password.
  4. Incoming server: mail.yourdomain.com (or hostname/IP).
  5. Outgoing server (SMTP): mail.yourdomain.com (or hostname/IP).
  6. Username: usually your full email address.

These are the standard fields used by email clients for mailbox setup. :contentReference[oaicite:6]{index=6}

Step 6: Configure ports and security (important) #

Use one of these secure options (recommended):

Incoming (IMAP) #

  • Port 993 with SSL/TLS (recommended)
  • Port 143 with no encryption (not recommended)

Incoming (POP3) #

  • Port 995 with SSL/TLS (recommended)
  • Port 110 with no encryption (not recommended)

Outgoing (SMTP) #

  • Port 587 with STARTTLS (recommended)
  • Port 465 with SSL/TLS (also common)

These port recommendations are standard for cPanel/DirectAdmin mailbox connections. :contentReference[oaicite:7]{index=7}

Step 7: Test the connection #

  1. Use Test Account Settings / Verify (wording depends on your client).
  2. If the test succeeds, you’ll get confirmation and your mailbox will begin syncing.

Testing validates your login, server, port, and encryption settings. :contentReference[oaicite:8]{index=8}

Step 8: Finish setup #

Click Finish / Done. Your email client should now send and receive mail using your Hosticko mailbox. :contentReference[oaicite:9]{index=9}

Troubleshooting tips (when it doesn’t connect) #

  • Wrong password: reset the mailbox password in cPanel and retry.
  • Wrong username: use the full email address, not just the part before @. :contentReference[oaicite:10]{index=10}
  • SMTP fails: confirm SMTP authentication is enabled and use port 587 (STARTTLS) first. :contentReference[oaicite:11]{index=11}
  • SSL errors: try switching between 993/995 (SSL) and 587 (STARTTLS), and ensure the server hostname is correct.
