Issue Plesk Premium Mail Autodiscover

[drdna]

Server operating system version

Ubuntu 18.04.6 LTS

Plesk version and microupdate number

Plesk Obsidian Version 18.0.46

Hello Pleskians,
my autodiscover / autoconfig with Plesk Premium Mail is not working correctly.

When I test the output of :
curl https://www.mydomain.de/autodiscover/autodiscover.xml
or
curl https://www.mydomain.de/mail/[email protected]

gives me output of the /usr/share/kolab-autoconf/public_html/index.php file instead of an xml file...:

Same problem here. Any news in this bugreport?

 

[Peter Debik]

It is said that autodiscover is a separate option in Plesk Premium E-Mail. Is it enabled?

Other users report that to return to Plesk autodiscover, they added
[mail]
autoconfig.enabled = 1
to the panel.ini file.-

 

[Elompenta]

@Peter Debik Thanks, yes Premium Mail is enabled for one Test Subscription. I want to Test it if it make sense to build bigger environments.

The Web Access via webmail.comain.tld and the Smartphone Active Sync connection with the same servername works fine.
Outlook doesn't work, because they call the autodiscover.xml

And then the Plesk Server not deliver the expected xml output, instead plesk deliver the same PHP Output like in @drdna original post.

I have also created a case for that - #95201266.
But it sound a little bit creepy that i found only a few information in the web for this plesk feature.
Do you know if its its very rare used feature?
Do you think that i can create very big Setups (> 1.000 users) with your Plugin and it scale as expected?

Other users report that to return to Plesk autodiscover, they added
[mail]
autoconfig.enabled = 1
to the panel.ini file.-

But in the Knowledge base for the Premium is written, that is expected that the default autodiscover will be deactivated and replaced by an own autodiscover from the premium mail? Is this not right?

 

[Peter Debik]

Yes, Premium EMail replaces the default. That is why I asked whether autodiscover is enabled. The other setting is just an option.

Outlook has issues with autodiscover files that other software understands. I am not sure to which extent this applies in this case. Have you contacted Plesk support already? They will be able to find out more.

 

[Elompenta]

Thanks, yes i have already an open case for that issue. I will wait for a solution in the suport case.

You have already seen my other post so you know the problems.

Regarding this exact problem, you better of telling your customers to always use the manual setup.
Autodiscover tries to use ActiveSync for domains where it is not enabled or uses IMAP for ActiveSync enabled domains.

If it works at all, it will setup the domain of the subscription instead of the Plesk server domain as the mailserver, which would be fine if Plesk would secure the mail domain with an SSL certificate. Currently that will just prompt a certificate issue on Outlook and most other clients.

 

[Elompenta]

This topic is a horrible story..
The plesk support not really understand the issue, and the kolab plugin breaks existing non-premium mailboxes by behavior and file system changes inside the imap boxes :/

• I have closed the support case (hopefull a new case will be helpful)
• I have deinstalled the Plugin, and plan to try it on a separate play machine

At the moment i think it is not possible to provide premium-mail and non-premium-mail on the same server because the collab setting interference with non-premium mail users and breaks the default imap behavior.
