Whitelist workaround

Thu, 26 Oct 2023 13:58:15 +0000

Hello.

We use Nimblr for training. Since we active Kaspersky Security for M365, all their phishing simulations are blocked.

There is no specific domain name we can use in the whitelist. We could use the smtp sender or ip but there is no option for that.

help.

Secure Mail Gateway TLS support?

Mon, 09 Oct 2023 16:41:30 +0000

Hello - we are using Secure Mail Gateway, and the configuration options allow for basic requiring of TLS, etc., but it makes no mention on what TLS protocols and ciphers are actually available. We are getting this in the logs, but only from a single connection, and I can't get any visibility past the basic stuff on the webpage:

Oct 9 09:40:37 kemg postfix/smtpd[57824]: connect from sil-mta-dmz-02-pub.dol.gov[152.180.11.245]

Oct 9 09:40:37 kemg postfix/smtpd[57824]: warning: TLS library problem: 57824:error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher:s3_srvr.c:1407:

Oct 9 09:40:37 kemg postfix/smtpd[57824]: disconnect from sil-mta-dmz-02-pub.dol.gov[152.180.11.245]

How can I get more information into this? Clearly a cipher mismatch, but how can I tell what/why? The logs in web page are of no use with respect to this.

Thanks,

John

Server Update KSMS(port&List)

Sun, 06 Aug 2023 06:48:32 +0000

I used Kaspersky Security 9.0 for Microsoft Exchange Servers to protect the email server
And according to the security standards, I put restrictions on it to access the Internet.
And based on the information of the following link servers
https://support.kaspersky.com/us/kes11/settings/network/15038
And based on the updated list of servers, I opened the access to the Internet
But I get an update error، But when I give unrestricted access to the server, the update problem is solved، I think the problem is due to the update list of servers, and the update list of Security for Microsoft Exchange servers may be different from the list of servers in the list below.
https://support.kaspersky.com/us/kes11/settings/network/15038
Thank you for helping to solve this problem

SPF macros

Tue, 06 Jun 2023 22:10:12 +0000

Hi!

Today we received an email from 143.55.144.8 and the sender's domain was danone.com. The email ended up in SPAM, the reason was:

X-KLMS-AntiSpam-Auth: dmarc=pass header.from=danone.com policy=none;spf=permerror smtp.mailfrom=danone.com;dkim=pass header.d=danone.com

The SPF record is:

v=spf1 include:%{ir}.%{v}.%{d}.spf.has.pphosted.com ~all

The MX toolbox says it's fine:

https://mxtoolbox.com/SuperTool.aspx?action=spf%3adanone.com%3a143.55.144.8&run=toolpage

But other tools say it is wrong:

https://www.spf-record.com/spf-lookup/danone.com?ip=143.55.144.8

Is it possible that KLMS does not support any of these SPF macros?

KLMS Version: 8.0.3.30

Thanks!

Any updates for this products planned?

Wed, 15 Feb 2023 13:11:09 +0000

Hello,

according to https://support.kaspersky.com/KLMS/8.2/en-US/148809.htm the product needs a Debian GNU / Linux 9.3 or a Ubuntu Server 16.04.4 LTS.
Both OS are already EOL. If installed on newer OS versions kmsui won't run since the systemlibraries are too new and incompatible.

Are there any new versions planed?

Regards,
Sebastian

Removing X-KSE-ServerInfo from header

Wed, 21 Sep 2022 13:34:52 +0000

Hello,

I would like to hide all the local information’s on the emails that are sent to the outside (internet) but after making a lot of changes i found that a header is added automatically when the message is scanned by Kaspersky security for mail server.

the most important information that I want to remove is the "X-KSE-ServerInfo:my_local_servername» which shows the local name of my SMTP server.

is there anything i can do to remove it?
thank you.
