No mail can be sent from the security camera

When I try to send emails from my security camera via the MIAB server, I get the following error message:

Feb 22 17:29:08 mail postfix/submission/smtpd[15496]: connect from[]
Feb 22 17:29:11 mail postfix/submission/smtpd[15496]: SSL_accept error from[]: -1
Feb 22 17:29:11 mail postfix/submission/smtpd[15496]: warning: TLS library problem: error:14209102:SSL routines:tls_early_post_process_client_hello:unsupported protocol:../ssl/statem/statem_srvr.c:1655:

Feb 22 17:29:11 mail postfix/submission/smtpd[15496]: disconnect from[] ehlo=1 starttls=0/1 commands=1/2

Sending mail from Outlook or other programs works without problems.
Anyone have an idea what this can be?


Do you know what encryption the camera supports?

Your email client (in this case the camera’s internal software) most likely uses an old depreciated version of TLS, or ciphers. Ask the manufacturer to provide you with software utilizing up to date standards.

If that is not possible there are other workarounds. Search this forum for posts about old printers. The issue and solutions are the same.

Here is one of many such threads:

Supportet TLS Version from the Cam are:
TLS 1.1
TLS 1.2

May be a cipher issue, as MiaB should be configured to support TLS 1.2 and 1.3.

Do you have any idea how I can fix that?

The camera uses a self-signed certificate. is that the problem?

No, it won’t matter based on current default MiaB settings.

In regards to cipher issues and assuming that is the problem, I don’t know how to fix that other than to see if there is a firmware update for the camera, replace the camera, or, as @Alento suggested install a local mail proxy.
