Reverse DNS

So after setting everything up on my side I figured mail was sorted....... Wrong. Users started to complain that they where getting bouncebacks giving an error about authentification:

" gave this error:
Not authenticated, please enable SMTP Authentication in email software and check login credentials
A problem occurred during the delivery of this message to this e-mail address. Try sending this message again. If the problem continues, please contact your helpdesk."

After a long time looking around a great exchange Guru on technet pointed me to this site

You put the email domain in and choose lookup. Then select mx lookup and then click smtp next to the MX record. For me this showed that reverse DNS had failed. It also came up with a few other errors which I resolved.

After much research I found that reverse DNS has to be set by the ISP. I contacted the ISP who hosted my domain and asked them to create reverse dns to match the A record that was set for mail. eventually I received a response that they did not own the IP I wanted the record for. Turns out although they hosted the A record ad such and hosted the domain they did not provide our internet IP address range. I contacted the ISP who host those IP's did asking the same.

They changed it and it worked.

First page is blank when printing through Citrix


After searching the internet I found this solution to why certain printers print blank first page through Citrix(xen app for me) so I thought it was only right to share.

On your local device click devices and printer or printers and faxes depending on the operating system. Then double click the printer you want to use through Citrix, When the print queue box opens goto file then properties. Then in the advanced tab at the very bottom untick "enable advanced printing options"

To create a new distribution group use the following command changing the red text to fit.

New-DistributionGroup "Test1" -organization "Yourorg" -managedby "Owners mailbox name" -PrimarySMTPAddress ""

get-distributiongroup "Test1" -organization "Yourorg"| set-distributiongroup  -RequireSenderAuthenticationEnabled $False

Part 9 - Securing email with anti spam on Exchange 2010 setup Multi-Tenancy

The next step is to secure your mail using the built in anti spam feature. To activate this use the following command in Exchange management shell to change the directory to the location of the script
set-location 'C:\Program Files\Microsoft\Exchange Server\V14\Scripts\'

Then in Exchange management shell type the command


Once this command is run you need to restart the transport service using the following command:

Restart-Service MSExchangeTransport

You can now view you filter settings using:


Once the service is restarted you need to change the filter slightly to enable it to work. Use the following command:

Set-RecipientFilterConfig -RecipientValidationEnabled $false

You may get a message that a value was not changed. This is ok as sometimes the default is set to true and this just swaps it.

You will then need to set the internal smtp permeter to enable the anti spam on all your email servers. Use the following command. Replace the red text with the ip addresses of your exchange servers(seperated by commas)

Set-TransportConfig -InternalSMTPServers,

From this point you should then consider wether you need further protection. If you do then Forefront protection is a great bet.
