Hello, i’m try to connect to my own imap (dovecot) server, but i see in logs:

Sep 28 23:01:34 cloud dovecot: auth: Debug: auth client connected (pid=16892)
…

When i use same certificate on Thunderbird, all is ok.

Please say me how to coax eM Client use specified certificate to establish ssl/tls connection.

Thank you for support!

Hi Valentin,
try looking into Tools > Accounts section and for the affected address try changing the Security policy under IMAP tab. I recommend trying the (legacy) option.

Best regards,

Hello, Olivia!

Thank you for the answer.

Yes, i “Use SSL/TLS on special port (legacy)” option in account settings, but in progress connection server request my personal certificate issued by my personal PKI and eM client does not send them. I think because eM Client using personal certificate only for signing and encryption message body, but i need encrypt ssl connection with them. In addition i can’t find in Tools > Accounts -> IMAP option which would indicate which certificate to use for build SSL connection.

Is it possible extension of functionality of eM Client?

Thank you for support!
