Hi!  New to this list and this product.  I posted this on the Amazon forums, but I need to fix this fast, so I thought I would post it here as well.

I am running stunnel 5.04 for Windows on a Windows 2012 R2 instance. I have it working with SES, but after a while it just keeps timing out. I have to manually reload the configuration file to get it to start working again. What am I doing wrong?

Here is a part of the log:

You can see that it stops, then I reload the configuration and it works again, and then eventually stops. Here is my configuration file:

engine = capi

cert = stunnel.pem

options = NO_SSLv2

ssmtp
accept = 465
connect = 25

smtp-tls-wrapper
accept = 2525
client = yes
connect = email-smtp.us-west-2.amazonaws.com:465

Thank you.
