Hello,

I'm struggling with SSL/TLS and IMAP server. Tried to install certificates with commands bellow but have no success. After executing test in IA->System.Conf->Mail->Attendand Mailboxes->imap account->Test, in testing window there is error: 
//

//
Before that I executed a couple of commands to get certificates from IMAP server.
E:\I3\IC\Server>ssl_app-w32r-21-2.exe s_client -showcerts -connect imap.server:993

then renamed temp1.cer and temp2.cer with corresponding hash names.

So files in certificates folder for email looks:



But after above test there is error in imapconnector log

CI3MailIMAPTransport::CheckCommand() : received error:Failure in TLS handshake - os-error code:0

CI3MailIMAPTransport::CheckCommand() : Throwing exception:IMAP_API_ERROR: CI3MailIMAPTransport::CheckCommand - command (ConnectTLS) failed to execute. [d:\builds\eic_2021r2_p01\products\eic\src\UMMessaging\CI3MailIMAPTransport.cpp:227]
Error (10):TLS Handshake Error



Please can you share your knowledge about configuring SSL/TLS with IMAP and CIC? Is there anything what I missed to configure in CIC?

Thank you very much for help, hints and advice

Best regards
