When I used SMTP with SSL mode, got some error:

When I use SMTP with plain Mode(port:25), It's OK.

Hello @bbqi - I tried to reproduce this situation but I am unable to.

Please make sure that you have the latest updates and try again https://zato.io/docs/3.2/admin/guide/install/update.html

If you still get an exception, please provide all the details of your connection, not just the traceback. Otherwise, I just do not know what your configuration is.

Thank you.

Closing due to inactivity. @bbqi - please feel free to reopen when you have all the details that I requested earlier. Thank you.
