Did you give them the private key, or generate the keys in the hosting control panel? They might already have it and have installed it in the right place to turn on signing.  If you still have the public key in DNS then you could try DKIM Validator or About My Email to see if messages are being signed.
Your hosting control panel may well hide which mail server it is using to avoid confusing customers with product names.

Thanks again... do my website hosting company need to set to sign outgoing mail?  They just told me to create the DNS record in my domain settings... which has been done, but can be deleted of course.  I cant see where Postfix or Exim is in my control panel....

I would recommend not putting the DKIM key in DNS until you have your mail system set up to sign outgoing email.
Where you put the private key depends on which mail server you use. It doesn't go in Outlook, Thunderbird, Roundcube, or any of the other email clients.  It goes in the mail server, which is often something like Postfix or Exim, and probably provided by your hosting provider.  You can often log into your hosting control panel and paste the key into the appropriate place to get signing working.

Thank you showfer .... very helpful.  Couple of queries.... when you say the private key in my email system, do you mean MS Outlook?  I cant see where you could add this info.  I have currently put the private key in the Domain Settings (which is a TXT record) with my Hosting provider and thats it (so it will presumably apply to all emails within the domain).  I think this is actually where you mean.  I have just checked and the public key is 'inside' the private DNS key.... so presumably anyone can see and generate the public key... or do i need to insert it somewhere as well?  Many thanks.  Matt

You put the private key in your email system so it can sign outgoing messages.  You put the public key in DNS so that anyone receiving email from you can verify the signatures.
The DNS entry is a TXT record such as newyork._domainkey.domain.tld.  You can have multiple "selectors" so that different departments can have their own DKIM keys.
Once you have signing and DNS set up, you can test it at places like https://dkimvalidator.com/ and https://aboutmy.email/ (and many others).

Hi

I am using roundcube to route my emails for my domains and I am trying to get my emails signed with DKIM.  I have generated the keys I need for the DNS records on my domain, but there is a private and a public key and I am not sure which one to use. 

The website I generated the key on seems to suggest the private one is needed.  I have added this kid at the moment, but the DKIM has not yet been implemented (I know this is not instant and can take some time).

Does anyone know which record I should be using?  Also, does anyone know how long this normally takes to run through the system and finally is there anyway I can easily check if it has been applied to my DNS settings?

Many thanks in anticipation.

Matt

I can't really answer that because it depends on how your Roundcube is configured. I think the only thing you could do is, in Roundcube, go to Settings > Preferences > Special Folders. On that screen, unless SiteGround have disabled it, you should see which folder Roundcube is set to treat as your Spam/Junk folder and change it or disable it.

@JohnDoh,

thanks for your reply.  so does that mean SiteGround added the unremovable "spam" folder?
they say 'no', that its a part of RoundCube.

the "Junk" folder is the one being used for junk/spam. so then where is this extra useless "spam" folder coming from? if not SiteGround, and if not RoundCube, then where? i would like to ask whomever is responsible for it to kindly remove it -or- give us the ability to "hide" it in IMAP just like we can hide it in webmail.

I would need to understand more of the use case to recommend similar plugins or hooks to use. Roundcube ships with a number of plugins in the plugins directory so it would be a good idea to start there.

Here is the documentation around building a plugin:

• Plugin API
• Plugin Hooks
• JS Plugin Hooks (I don't think this list is complete)

Hi all,

I've recently started using Roundcube and it's proving pretty handy for managing emails via the web. I've noticed there's quite a bit of scope for customisation and plugins, which is great for tailoring it to one's needs.
I've also come across platforms that offer loads of resources for startups and developers, like programmes, offers, and support for all sorts of tech tools (for example, places like https://gritt.io/). I'm wondering if there's anything similar specifically for Roundcube, or if anyone here uses services or plugins from those kinds of ecosystems to boost Roundcube's capabilities.
Specifically, I'm trying to hook up an external tool (think API or plugin) to improve the user experience, but I'm a bit lost on where to start or whether there are ready-made solutions out there.
Has anyone had a go at this sort of thing before? Any advice on where to find solid plugins or tips for building your own?

Cheers in advance!
