Question Error in the panel when selecting a webmailer

[m.angenendt]

Server operating system version

Ubuntu 22.04.5 LTS

Plesk version and microupdate number

18.0.72

When I want to change the webmailer for a customer, I get the message ‘This option is not supported.’ / 'Diese Option wird nicht unterstützt.'
Regardless of whether I want to use Roundcube, SoGo or a predefined webmailer, the email settings can only be saved if I select ‘None’.

Unfortunately, a plesk repair DB or repair mail domain does not help.

I have checked the packages and definitions but could not find any settings that cause this.
Does anyone have any ideas?

Under Tools & Settings > Webmail do you have them enabled?

Yes it is enabled.

After a long search and various tests to reproduce this on other domains/servers, I have now found what is causing the problem, but in my opinion it is a bug.

The customer had forwarded webmail.domain.tld to the webmailer URL we provided.

Plesk then said that there is a webmail.domain.tld and that you cannot select a webmailer, which is fine if you want to put webmail.doman.tld on your own application, but not if it is a different URL that is to be given to the customer as a webmailer. This is so that they have the link there behind the email address, for example.

If they add the subdomain webmail manually and make a forward, then it's not a bug that you cannot set up webmail there, since Plesk cannot add a web configuration if it already does exist for something else. But also depends on how they did set up that forwarding.

Sorry for the late reply. If it's just about setting up webmail.domain.tld at this point, I would agree with you, but that also sets the information behind the email accounts where users can find the webmailer.

If I have now created, for example, webmail01.mydomain.de for all customers and registered this as the central webmail URL, I want this to be displayed in the interface for the customers. Since webmail.domain.tld is not set, this is a bug for me because I cannot select it.
