When I try to send Emails I get a warning 'TLS for outgoing emails is activated'.

After installing Lavasoft Anti-Virus Helix, it might happen that you can not send emails. A warning may appear: TLS connection detected. Email sending blocked.

The TLS (Transport Layer Security) encryption protocol is not yet supported by MailGuard. You can:

  1. Turn off the scanning of outgoing emails in Anti-Virus Helix MailGuard settings, or
  2. Set another SMTP port instead of port 25, or a different connection type altogether, in your email Client.

1. Turn off the scanning of outgoing emails
If you can not set another SMTP port or connection type in your email Client, turn off the scanning of outgoing emails in Lavasoft Anti-Virus Helix configuration, as described below:

  • Open Lavasoft Anti-Virus Helix
  • Click on Configuration -> MailGuard
  • Activate Expert mode
  • Go to MailGuard -> Scan
  • Deactivate the option Scan outgoing emails (SMTP)
  • Confirm with OK

The protection for incoming email remains activated.
