Questions about sending and receiving encrypted email

May 8, 2014, 11:01 am

When you send out an unencrypted, digitally signed message or a message with your public key attached (so you can send encrypted messages to them in the future), can't that message be intercepted and then the "hacker" would then have access to read any of your future encrypted emails they intercepted in the future?

When you send an encrypted email, if the recipient replies without actively selecting options to encrypt their reply, is your previously encrypted content in the body of the message now sent back to you over the Internet in clear text?

If you send an encrypted message to someone and the recipient has an Outlook rule that forwards messages to another account (gmail etc.), is the message still protected with encryption when their Outlook rule forwards the message?

I created an internal only receive connector using only the anonymous permission this worked but resolution did not. I found to get resolution I need to enable externally secured this required exchange server permission. it will now resolve but is no longer internal only. when I look at ad permission for anonymous send to any recipient is not checked.

What do I need to set to have internal only receive connector that will resolve internal names?

Redirect messages sent to distribution group

I have a need to set up a hub transport rule as follows:

If recipient is a particular distribution group

And If subject contains "String A" or "String B"

Then Redirect to these specific people

It would appear that I cannot use a distribution group as the recipient if I want to redirect.  Is that accurate?  Any ideas on how to work around this?

Cannot enable custom DSN

Hello,

I am trying to create a custom DSN to send a NDR alerting the internal sender that his/her mail has been rejected due to profanity.  I created a DSN 5.2.9 with the message "Your message appears to contain profanity or unprofessional language - please correct before re-sending"  However, when i try to apply the DSN to the rule I get "The value that you entered cannot be saved because it contains the character "5".  To save this, you must first configure a custom delivery status notification.

What am I missing that would cause the server not to recognize that there is a custom DSN?  Note that from powershell, the server returns the correct message when I enter Get-SystemMessage.

Relay Receive Connector - Recipient Limit is not respected

Hi,

I have configured a Relay Receive Connector for an application and I set the Recipient limit for it, 50 recipients.

Unfortunately this limit is not being respected, the application can send emails to about 70 recipients without block the message.

I have a Receive Connector for my users and it is working well.

My question is, is any kind of difference when a relay receive connector is configured or it is a bug?

Thanks in advance.

Best Regards.

Hello,

I have an on-premises environment where I have an exchange 2010 hub and edge server. I have 4 domains. All my emails are routed through edge server to the internet. When I send an email from my primary domain to a particular remote domain the email gets delivered. When I send an email from any other secondary domain the email does not get delivered at the remote end. The remote domain is on office 365. 

I tried sending the email with the delivery receipt to the remote domain from my secondary domains and I always get the delivery receipt stating that the email has been delivered however the remote domain admin says that the email was never received by him. We have also did the message trace on Office 365 remote domain but there was no trace of that email.

Please help and let me know how can I proceed futher this is hampering the productivity in my organization.

Hello There,

I’m going to proceed with migration form exchange 2007 to 2013 but just encounter problem.

I can telnet port 25 form new Exchange 2013 server but cannot telnet it form any other computer within LAN. 

We have notice it when I was changing SMTP banner to match RevDNS. If I change Receive Connector to role Hub Transport it is responding on telnet 25 from other servers. But correct is to set it up as Frontend Transport.

There is no AV and Friewall is disable. I can telnet prots form hubtransport role receive connectors.

Fresh installation and server is fully updated. Please help.

Hi 

We are getting below error on few of CAS servers when we try to upgrade to Exchange 2010 SP3 while uninstalling the IU for SP2

"Setup wizard for update rollup6 for Exchange Server 2010 Service Pack 2 (KB2746164) ended prematurely because of an error.Your system has not been modified.To install this program at a later time, Please run the installation again"

We checked UAC its disabled for the server.

Tried running with run as administrator in the source patch file as well still did not help

Tried opening the source file as copy as path in command prompt and running them as well still it did not help

We tried manually uninstalling the Interim Update but still we get the same above error

Any help would be much appreciated.

Restricting Incoming Mail to deliver during office hours

Hello

Can you restrict Exchange (2007) in my case to deliver email to users during certain hours of the day.

Currently we have several users asking as they are getting email coming into their phones late at night or in the early hours of the morning.

They want to leave their phones on and not have to keep disabling emails on phones when they go to bed or example so I wondered if there was something we could do on the server to only allow mail to be delivered during certain hours of the day on the connectors.

Help appreciated

thankyou

outbound email IP address returns firewall ip not mx record ip

Hi all,

We are sending emails fine but some are rejected from some SMTP domains withy the message below:

'450 4.7.0 Proxy session
setup failed on Frontend with '451 4.4.0 Primary target IP address responded
with: "554 5.7.1 Delivery not authorized no reverse DNS record exists for
your connecting IP address." Attempted failover to alternate host, but
that did not succeed. Either there are no alternate hosts, or delivery failed
to all alternate hosts. The last endpoint attempted was ....

I searched on the outbound email IP from one of my sent emails to an external email and it was not the MX record IP, it was the firewall IP that is why it is blocked (as some email systems check for reverse DNS entry that points to your email server and the firewall do not have one in public DNS). My question is how to solve this? Is it by simply adding a RDNS record in public DNS for the firewall IP to point to our mx record or changing the route traffic on firewall? What are all our options?

Note: SPF wizard states that there is no SPF record found but there is an A and MX record currently exist for this domain (our SMTP domain)

Exchange Anti-Malware and Trend Micro

Hellow,

I am finalizing an Exchange 2013 deployment and I have a question:

I have installed Trend Micro as the anti-virus solution for my exchange servers, but this is a file-level protection software, I guess it doesn't protect my Exchange, rather it protects only the windows server environment.

Should I enable the Exchange 2013 built-in anti-malware protection along with the trend micro? If it´s not recommended, which one should I choose to keep?

Thanks in advance.
