How to edit the Email Client Setup Settings in Plesk Obsidian?
To help your customers set up an email client manually, the “Manual Setup” section (Websites & Domains > the domain > Mail Accounts > the icon) shows the information about the necessary settings. You can change this information by editing the panel.ini file which is useful in the following cases:
- Your mail server is secured with an SSL/TLS certificate (for example, assigned to
server.com) and you do not want your customers to see the “Untrusted certificate” error when they access their mail via an email client. To achieve this, you need to change the incoming and outgoing mail servers shown in “Manual Setup” to
server.com. Then the customers will also specify
server.comin their mail client settings instead of their domain names.
- You want to explicitly specify which ports the customers need to use in their mail client settings.
- You want your customers to use only secure protocols (POP3, IMAP, and SMTP over SSL/TLS).
- You want to hide the note about the “Untrusted certificate” error. By default, this note is shown when the corresponding SSL/TLS certificate is self-signed, expired, or the domain name in the SSL/TLS certificate does not match the incoming mail server name.
- You have any other mail settings that differ from default ones shown in the “Manual Setup” section.
To edit the email client setup settings:
Edit the values of the
clientConfig* settings (under the
[mail] section) in the
panel.ini file or install the Panel.ini extension in Plesk > Extensions. The full list of all these settings with their default values is shown on the screenshot below:
To change the
clientConfig.outgoingServer settings, use the
clientConfig.outgoingProtocols use plain text.
For example, you want your customers to use the server hostname as the mail server, to use only secure protocols, and do not want the customers to see the note about the “Untrusted certificate” error in the “Manual Setup” section.
To achieve this, add the following lines to the
clientConfig.incomingProtocols="POP3 over SSL/TLS, IMAP over SSL/TLS"
clientConfig.outgoingProtocols="SMTP over SSL/TLS"
