HESK 3.5.2

Hello klemen,
in Settings > Email, I turned on "Send email using SMTP server" and Test SMTP connection returns "Success: Connection successful!".
So far so good.

Unfortunately when trying to open a ticket I get this message (debug mode turned on):

Code: Select all

Note
Could not send email notifications. Cound not send the message to: <agent email address supposed to get the email notification>

Error: SMTP Error: Could not connect to SMTP host. Connection failed. stream_socket_enable_crypto(): SSL operation failed with code 1.
OpenSSL Error messages: error:0A00018A:SSL routines::dh key too smallSMTP server error: QUIT command failed Detail:
[...]

I looked for error:0A00018A on the web and I think I realized the problem is (mail)server side because it is probably using a too weak DH key (?)
Am I right? If yes, is there a way to make the client (HESK) use it anyway? I am afraid the mail server is note easily and readily upgradable...

Thanks.

Yes, that's an underlying server problem.

I don't know of a work-around, you will most likely need to secure the OpenSSL and the chiper the sever uses.
