Question
How to manage mail autodiscover in Plesk?
Answer
Autodiscover is enabled by default on all new Plesk Obsidian installations for all domains.
For Plesk versions upgraded to Plesk Obsidian or enabling it again on Plesk Obsidian it can be managed with the following steps:
-
Go to Tools & Settings > Mail Server Settings > Settings tab > General options > Enable the checkbox Enable mail autodiscover.
-
To enable autodiscover:
-
- for a particular domain, navigate to Domains > example.com > Mail Settings and activate the checkbox Enable mail autodiscover
- for all domains at once, follow the instructions of the article How to activate mail autodiscover for all existing domains on Plesk server?
-
-
A valid SSL certificate is required. Make sure it is assigned under Mail Settings tab or issue a certificate using "SSL It" including option Assign the certificate to mail domain.
-
This step is required only if you create DNS records directly under registrar and not in Plesk. Create the following SRV records manually under DNS registrar:
Record type Domain name Service Protocol Priority Weight Port Target SRV example.com _smtps tcp 0 0 465 example.com SRV example.com _imaps tcp 0 0 993 example.com SRV example.com _pop3s tcp 0 0 995 example.com
-
Autodiscover is not compatible with Outlook version 2019, 2021 and O365. These mail clients use Microsoft proxy servers for autodiscover requests, which is not supported in Plesk and Plesk Premium Email extension.
-
When a custom mail server is configured in Tools & Settings > Mail Server Settings, settings may not be obtained by some Android applications. It depends on the method used by an application to fetch mail settings using autodiscover.
The corresponding request https://jira.plesk.ru/browse/PPPM-13140 was created to address this.
-
It is not available for domains without hosting.
-
Domains with autodiscover should be secured with valid SSL/TLS certificate.
-
Plesk does not use "mail.example.com" or "imap.example.com". It uses domain name itself like "example.com" as SMTP/IMAP hostname for automatic configuration.
-
Plesk Premium Email has it own configuration for autodiscover. When it is installed, above autodiscover management of Plesk is automatically deactivated.
