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 https://forums.aws.amazon.com/ accept = 465 connect = 25
smtp-tls-wrapper https://forums.aws.amazon.com/ accept = 2525 client = yes connect = email-smtp.us-west-2.amazonaws.com:465
Thank you.
