Hi. Here is changelog entry about some interesting "Mail hosting" feature :

Where can I read more details about this?

Also on 18.0.64 I can only choose "website hosting", "redirect" or "none" in "add domain" dialog
 
Don't think there's any details about it directly, it's just an option you choose when adding a new domain as see in the screen shot below1727340081575.png

This basically just sets the hosting type to No Webhosting allowing just for the email function.
 
Thank you for additional information, so this option is only available with applicationWizard.enabled = true in panel.ini , old "add domain" interface has no "mail hosting" option
Also I'm still interested in addition info or documentation for this feature.
 
You should have both applicationWizard.enabled and applicationWizard.mailHosting set to true:

[domainManagement]
applicationWizard.enabled = true
applicationWizard.mailHosting = true

I believe they should be enabled by default, but if some adjustments are made on your server, please add the aforementioned code to panel.ini and you should be able to see the option. If you still don't see it afterward, please let us know.
 
No, I am afraid, there isn't dedicated documentation for that particular feature. However, if you have any specific questions, please let us know and I will do my best to gather the necessary information for you.
 
Thanks. First question - After this new feature released can I add "mail only" (without hosting) domain in subscription if it's not the first domain in it (first one with hosting, wordpress or etc...) or can I add domain with webhosting if first domain was "mail only"?
Some time ago there was a restriction Resolved - Can't add additional domain
 
If the subscription itself is configured as "Mail Hosting" you will not be able to configure additional domains with hosting option unless you adjust the "Hosting type" from Subscriptions > example.com > Hosting & DNS > Hosting. The same behavior described in the old post you linked. However, if the subscription has hosting option enabled, you can configure all newly added domains with the option you prefer.

1. Do I understand correct, that if I use quoted "wizard" to create new "mail hosting" domain - it's the same if I create "blank website" with mail enabled service and after creation I disable webhosting?
2. How can I create service plan for "mail hosting" and add "hard disk quota" for that plan?

Yes.

The "hard disk quota" only applies to webhosting, it has no effect on the limitation of disk usage for email.

So I can create service plan with disk limit but can't actually limit user to use only described limit?
Click to expand...
You can (well sort of). When you create a service plan on which overusage of resources is not allowed, the subscription will be suspended whenever more resources (such as disk space) are used then the resources limit defined in the service plan.

Yes, thanks. But as I said, this is not hard limit.
As I know, "overuse is not allowed" functionality checks overuse one/few times a day, so between these checks user can upload much more.
Why I asked, because yesterday one user with 25GB disk limit sent 50Gb of emails (all of them saved in Sent and used 50Gb of disk)
What's why hard disk quota is needed even if webhosting disabled
 
I see. You are right, "overuse is not allowed" is not a hard limit and there currently is no option to set a hard limit for the total disk space usage of mail on a domain. However, there is a hard limit for the disk space usage of individual mailboxes.

Yes, that would be nice to have :)
 

I would say it is a technical limitation. Autodiscover ("Automatic configuration for mailboxes") requires access to a special page (e.g.: "https://<domain>/autodiscover/autodiscover.xml", "https://<domain>/mail/config-v1.1.xml[...]", "https://<domain>/email.mobileconfig[...]", depends on a mail client/protocol); the page should be secured with SSL in some cases.

If you disable web hosting for a domain or point the domain to another server, the auto-discover will not work.

Also, in the next release, we will allow customizing the content of the Configure Mail Clients page. You will still not be able to use Autodiscover with disabled web hosting, but with this feature, you can modify the content as you want (within reasonable limits).
 
There is no ability to change what <domain> to use for auto-discover; the domains/paths are "hard coded" on the email clients' sides because this is a part of the protocol that describes where and how to find the valid settings; that is why applications know what link use. This means that for https://webmail.test.com, emails should be like user@webmail.test.com.
 
Oh, thank you for detailed description.
But anyway, https://<domain>/autodiscover/autodiscover.xml is not hosted directly in the sudfolder of <domain> , right?
So if <domain> is pointing to my server and "Mail hosting" selected - there is a possibility to create webserver config to make special pages works (e.g.: "https://<domain>/autodiscover/autodiscover.xml", "https://<domain>/mail/config-v1.1.xml[...]", "https://<domain>/email.mobileconfig[...]", depends on a mail client/protocol); , what do you think?

Then we are a step away from enabling Web Hosting :-D

It reminds me that it is possible to customize web server configs in Plesk, Changing Virtual Hosts Settings Using Configuration Templates. But I am not sure if it will work with auto-discover end-points or not.

Anyway, I got your idea and will discuss internally the possibility/cost/etc.
