Expired external S/MIME certificates not highlighted in webadmin and still used for mail encryption

Peter Schäfer

I found 1 article with this topic, written 3 years ago.

UTMgeek´s Answer: 

  Hello CS, 

  We acknowledged the issue and its make sense to highlight those certificate on webadmin to draw quick attention for certificate update. We will explore possibility to add highlighting option in future version. Stay          tuned !

It seems nothing changed since.

In my case, the UTM used an outdated Certificate to encrypt, last week.

Sending an email signed with my new Cert doesn´t work, to update the old one.

I deleted the old one  via api and sent a signed mail again. No success. New cert isn´t imported.

In webadmin  "Email Protection/Encryption/SMIME Certificates" it is not possible  to filter anything else Name.

    Hallo Peter and welcome to the UTM Community!

    I'm not sure what it is you're asking us.  In my system, outdated certs are removed automatically from WebAdmin.  Are you saying that the old cert is still in the database, but just not shown in WebAdmin so that the cert is used even though we don't see it in WebAdmin?  Are you also saying that if you send an encrypted email with a new SMIME cert to the UTM that it doesn't strip out your new cert?

    What do you see with the following at the command line any past the expiration date?

    cc get_objects emailpki smime |grep 'expires'

    Cheers - Bob

    Hi Bob,

    i´m late, sorry!

    outdated certs are not removed, cc gives me a long list.(447 certs  starting 2015).

    216 certs expired before 2020.

    Wow, that has to be a BUG - please get a support ticket open so this can get escalated to the developers!  You might also mention that expired 'Local S/MIME Authorities' continue to appear in WebAdmin with no indication they've expired.

    Schöner Fang, Peter !

    Cheers - Bob

    this is the answer i got in response  of my ticket:

    I apologize for the inconvenience but as I checked in the firewall and consulted further, this is the default behavior of the UTM as of now. It encrypts as long as it matches.
