Avast has blosked to smtp mail

A frustrating issue!

Avast is a popular antivirus software that sometimes blocks legitimate emails, including those sent via SMTP (Simple Mail Transfer Protocol). Here are some possible reasons and solutions to help you resolve the issue:

Reasons why Avast might be blocking SMTP mail:

  1. False positive detection: Avast might incorrectly identify a legitimate email as malicious, blocking it from being sent or received.
  2. Outdated virus definitions: If Avast's virus definitions are outdated, it may not recognize legitimate emails and block them.
  3. SMTP server settings: Incorrect SMTP server settings or configuration issues might cause Avast to block emails.
  4. Firewall or network issues: Firewalls or network issues can prevent Avast from communicating with the SMTP server, leading to email blocking.

Solutions to resolve the issue:

  1. Update Avast virus definitions: Ensure that Avast's virus definitions are up-to-date. You can do this by opening Avast, clicking on the "Menu" icon (three horizontal lines), and selecting "Update" > "Update virus definitions."
  2. Configure Avast to allow SMTP traffic: Go to Avast's settings (usually found in the "Menu" > "Settings" > "General" > "Exclusions") and add the SMTP server's IP address or domain to the "Exclusions" list. This will allow Avast to recognize the SMTP server as a trusted source.
  3. Check SMTP server settings: Verify that your SMTP server settings are correct. Make sure you're using the correct server address, port number, and authentication credentials.
  4. Disable Avast's email scanning: If you're experiencing issues with Avast blocking emails, try disabling email scanning temporarily to see if it resolves the issue. To do this, go to Avast's settings (as mentioned above) and toggle off "Email scanning."
  5. Contact your email provider or IT administrator: If none of the above solutions work, reach out to your email provider or IT administrator for assistance. They may be able to help you resolve the issue or provide additional guidance.
  6. Consider whitelisting the SMTP server: If you're using a custom SMTP server, you can try whitelisting it in Avast's settings. This will allow Avast to recognize the server as a trusted source and prevent it from blocking emails.

By following these steps, you should be able to resolve the issue and get your SMTP mail flowing again.
