No mail can be sent from the security camera

[Syc0nd]

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 p5dce1ecf.dip0.t-ipconnect.de[93.206.30.207]

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?

Anyone have an idea what this can be?

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:

Allow internal network devices to send email with insecure connection

Dear all, I just moved from Iredmail and I must say that i fell in love with MIAB. Simple and it is working like described. I am facing a small issue. I have Samsung MFP and before on Iredmail I needed to change /etc/postfix/master.cf with the following 2525 inet n - - - - smtpd -o smtpd_sasl_auth_enable=yes -o smtpd_sasl_security_options=noanonymous to allow for the printer to send insecure email via port 2525. I have tried the same with MIAB but fa…

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.

[Syc0nd]

Do you have any idea how I can fix that?

[Syc0nd]

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

[openletter]

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.
