Greetings, We have been using Stunnel 4.26 to facilitate the sending and receiving of email with an email client that is not SSL enabled. Version 4.26 has been working great. However, when we upgrade to 4.27, we are unable to POP email (we can send email). We did not change our Stunnel.conf file.
Can anyone advise us what we need to do to get 4.27 working? I've included our Stunnel.conf file contents, and the Stunnel log output below.
Regards,
Jeff
