DKIM has been around for a while now. Considering the lack of support from Microsoft and the inability of Exchange (even 2013) to natively add DKIM signatures, I would absolutely appreciate having this function in the Barracuda.

Actually, I'm somewhat surprised that it isn't already there and very surprised that I didn't see several other requests to add this feature.

I requested this back in 2011. I agree with you but don't hold your breath.

I agree with Nelson and Eric. I was checking into this today and was surprised that the Barracuda SPAM and Virus Firewall does not provide this functionality. It was important enough to be programmed into the system to allow for checking of DKIIM but apparently not important enough to provide DKIM signing for outgoing email. Anyone know if this it going to change anytime soon?

Another vote for outbound DKIM signing. It's really the only feature that's missing from Barracuda Spam Firewall.

Can we get some official response on decision and ETA?

Yes, we need DKIM on outbound mail.

I would like to add my support for this to be added in a future release. We currently use Barracuda as the MTA between our internal Exchange infrastructure and the Internet. I would love to add DKIM to all our outgoing messages.

Maybe Barracuda Networks could put up a list of potential features, where forum users could assign priorities. Thus giving BN an indication of what customers actually want.



Sooo.... they have that already.

Since 2011 i am asking Barracuda to add DKIM on outbound emails.

Without success.


The latest Firmware for the SPAM Filter is now 5 Monts old.

Maybe they decided to not develop something new from now on ;)

I also would like to have DKIM signature for outbound mail!

Such a basic feature, and it's missing...

I agree, outbound DKIM support is a MUST.


We have multiple domains we need to send mail from and some of our 3rd party mailers for things like alerts and such now REQUIRE us to add DKIM records for them to send out mail on our behalf. We're now getting to where we need to send email out from the same domains from our own Exchange server and we'd love to see our Barracuda be able to use DKIM so we don't have signed emails from a 3rd party and unsigned emails coming from us directly.


DKIM might be slowly getting adopted but I do think it's gotten to the point that it can be considered a basic feature to expect businesses to have implemented on their email servers. Yes, not everyone validates DKIM signatures and it's not going to create a panacea of a spam free Internet, but if it helps cut down on spam at least a little bit it'll be worth it.

Both DKIM signing and DMARC functionality is highly wanted.

This is become more and more essential, no longer just a nice-to-have. Please add DKIM signing into future releases.

I'm surprised DKIM is not adopted by barracuda email security service. I guess it's time for me to try othe vendor such as sendio.

Barracuda, better listen to us, or else you will loose clients. Also, does anyone know if they are usi that old Bayesian method to categorize spam?

As an Exchange user, I also think this would be a valuable addition to the platform.

I agree with the others here.  DKIM signing should be top priority. Could someone from Barracuda please give an update on this?

I am flabbergasted that we still have no outbound DKIM support.

No inbound DMARC support either, as far as I can tell. 


I guess I'm going to have to find a third party solution to implement DKIM. It's shame that I will have to needlessly add more complexity into our e-mail infrastructure just to get a basic feature that should be covered by the Barracuda solution that we pay a whole lot of money for.
