Hi there.
We have an issue with the Email Account for incoming mails.
The last connection was to our Exchange Server and since upgrading to Version 4.0 the incoming mail section shows this Error Message:
Can’t use Channel::Driver::Imap: #<OpenSSL::SSL::SSLError: SSL_connect SYSCALL returned=5 errno=0 state=SSLv3/TLS write client hello>
I don´t know what to do to fix this. Could somebody help me?
Server: Ubuntu 20.04 lite Server
Zammad Version: 4.0.x
