MailDev with Symfony 5 Mailer TLS crash

I'm working on my local machine on a Symfony 5 project. To test some mail functionality, I decided to use Node.js MailDev package.

The problem is that I found that MailDev does not support TLS encryption at this moment (version 1.1.0), and I found nothing on Symfony Mailer configuration that's allowed me to disable mail encryption.

When I try to send an email with encryption, MailDev server just crashes.

How can I solve that?

Thanks,Navalex
