Avast blocking mail server

Frustrating!

Avast is a popular antivirus software that can sometimes block legitimate email servers, including mail servers, due to various reasons. Here are some possible causes and solutions to help you resolve the issue:

Reasons why Avast might be blocking your mail server:

  1. False positive detection: Avast might incorrectly identify your mail server as a malicious server, leading to blocking.
  2. Outdated virus definitions: If Avast's virus definitions are outdated, it may not recognize your mail server as legitimate.
  3. Firewall settings: Avast's firewall might be blocking the mail server due to misconfigured settings.
  4. Email client settings: Your email client's settings might be causing the issue.

Solutions to resolve the issue:

  1. Update Avast virus definitions: Ensure that your Avast antivirus software is updated with the latest virus definitions. This might resolve the issue if it was caused by outdated definitions.
  2. Add the mail server to the Avast whitelist: You can add the mail server's IP address or domain to the Avast whitelist to exclude it from scanning. To do this:
    • Open Avast and go to Settings (or Preferences, depending on your OS).
    • Click on "Exclusions" or "Exceptions".
    • Add the mail server's IP address or domain to the list.
  3. Configure Avast firewall settings: Check your Avast firewall settings to ensure that they are not blocking the mail server. You can do this:
    • Open Avast and go to Settings (or Preferences, depending on your OS).
    • Click on "Firewall" or "Network" settings.
    • Check the settings to ensure that the mail server is allowed to communicate.
  4. Check email client settings: Verify that your email client's settings are not causing the issue. Try changing the settings or switching to a different email client to see if the issue persists.
  5. Contact Avast support: If none of the above solutions work, you can contact Avast support for further assistance. They may be able to help you resolve the issue or provide additional guidance.

Remember to always keep your Avast antivirus software up to date and follow best practices for email security to minimize the risk of email server blocking.
