I am trying to get SSL working with POP, IMAP and SMTP. For some reason I cannot get it working on this server (Windows Server 2012 with SmarterMail 14.7).
All ports and bindings are correct, certificate is verified - followed all the instructions in the knowledge base. I have done this several times before on similar servers and never had an issue.
Running "openssl s_client -connect myserver.com:465" - same results on 993, 995.
CONNECTED(00000003)
write:errno=104
---
no peer certificate available
---
No client certificate CA names sent
---
SSL handshake has read 0 bytes and written 289 bytes
---
New, (NONE), Cipher is (NONE)
Secure Renegotiation IS NOT supported
Compression: NONE
Expansion: NONE
I have tried different certificates, same issue. May be something with Windows but https works and using Qualys SSL Labs the server receives an A rating. Running out of things to try, any suggestions would be appreciated.
