How to Check if Your Connection IP Is Blacklisted When Using a Non-Mweb Network

• If you are travelling, roaming, or using any network that is not part of the Mweb range, you may find that your mail app cannot connect to your mailbox. This often happens when the connection IP from that network is blacklisted for spam or security risks. Your mailbox is still fine. The issue sits with the network you are connected to.

  You can check this yourself and still access your email through Webmail.

  Step 1. Find Your Current Connection IP

  If you are not on the Mweb network, the simplest way to see your current public IP is to visit one of these sites:

  • https://whatismyipaddress.com
  • https://www.whatismyip.com

  Your IP address will the IPv4 address.

  Step 2. Check if Your IP Is Blacklisted

  1. Go to https://check.spamhaus.org
  2. Enter the IP address you found.
  3. Select Lookup.
  4. The results will show if that IP is listed on Spamhaus. A listed IP means the network you are connected to has been flagged. It does not mean your email account is compromised.

  Step 3. What to Do if Your IP Is Listed

  • Switch to another connection if possible.
  • If you are roaming, try mobile data instead of hotel or public WiFi.
  • If you are on a third-party network, restart the router to try for a new IP.
  • If the IP stays listed, contact the provider of the network you are using. They will need to fix the blacklist entry.

  Step 4. Access Your Mail Through Webmail

  Even if the IP you are using is blacklisted, you can still log into your mailbox through Webmail because the connection happens through Mweb’s servers.

  • Mweb Webmail: https://www.mweb.co.za/webmail
  • Log in with your full email address and password.

  This is the quickest workaround while you wait for the network provider to resolve the blacklist issue.
