I can confirm that this feature is on our 2023 roadmap. We have no ETA at this time, though we will update this thread once we are ready to roll the feature out.

Planning to move from FreshDesk to ZenDesk & testing different optons of ZenDesk, but found this SMTP option is not available. Will move on to this platform once this option is properly available.

Also @sean33, one option which I have complaint to FreshDesk and they have not resolve it yet. Option is that when sending emails from custom domain SMTP (not gmail or yahoo), it just sent email from our server but does not save in SentBox of the email address. In programming, we have to use SMTP for sending email and must add few lines of extra codes (like imap_append in PHP) to save sent email in SentBox. So please must provide this option or add some checkbox "to save emails in SentBox".

Just followed the thread and also upvoted. Keep us posted.

Adding a voice, here. This is something our IT department requires so that there is a record of all emails in and out of the organization - something I'm sure many others can relate to. The increased delivery reliability would be a bonus. Eager to learn when this feature will be available.

Last status update was in March, so we're another half-year on now. Any sign?

@sean33 We're at the end of November now, any ETA available please? 

Would love to see if it's possible to retain features such as CodeTwo (signature manager), to stop double handling of signatures in multiple locations (Zendesk & CodeTwo).

Should be implemented early last year... Now it's time to implement this feature. As Jarrad Richards told the signature Management is something important but also Mail signing and encryption... We all getting closer to use Mailrelay's for automatically sign and encrypt emails and this is at the moment not possible...

We are currently in development for an Authenticated SMTP Connector. We do not have an ETA for when that feature will be released. We will update this thread once we have more information.

Hello @sean33

Can I get a share of the development schedule?
I wonder when it will be released.
We are very interested in this feature.
It's a must-have feature.

Hi @sean33 

On March 2, 2023, you mentioned this was on the 2023 roadmap. On December 1, 2023 you mentioned this feature was under development.

 

As of the first quarter of 2024 Microsoft has started a slow roll-out of some mail handling processes to ensure their IP's don't end up on blacklists due to open relays forwarding too much spam. This now affects the consistent delivery from  our internal support address relaying to our Zendesk support address to create tickets, and I'm sure we're not the only Zendesk customer having issues. We have SPF and DKIM setup properly but that's not the solution, and never should have been the solution to begin with, any longer. We NEED the ability to setup authenticated SMTP leveraging an o365 account in order to maintain brand consistency with our support.

 

Could you provide any sort of update? I saw reference that this type of functionality exists within Zendesk Sell, so it's not like the knowledge to implement the solution is missing from Zendesk's internal development team. We're just all curious why it's been 8 years since this thread was first opened expressing similar concerns to today, and still not having a solution in place to address things.

 

Thank you.

The following link outlines the changes I mentioned as described by Proofpoint, but it requires a login so I'll also attach a screenshot to read: Proofpoint's Response on CIDR Range 40.95.0.0/16 Giving Relay Deny errors

Here is the link to the Microsoft documentation.

It seems you're dealing with Google Tag Manager code in your Zendesk instance. If you're looking to integrate or troubleshoot, ensure the container IDs (GTM-XXXX) match your intended tags and configurations in Google Tag Manager. This will help in effectively tracking and managing your tags. If issues persist, double-check if your Zendesk setup permits such scripts.
