Issue Summary

One or more mail servers use basic authentication warning displayed incorrectly

Steps to Reproduce

1. Configure all incoming mail servers in ⚙ > System > Incoming Mail to use the Oauth 2.0 authentication method
2. Configure the outgoing mail server in ⚙ > System > Outgoing Mail to use the basic authentication method

Actual Results

The incoming mail server page displays a warning that says:

One or more mail servers use basic authentication. This method is planned to be deprecated by Microsoft and Google. Update the authentication method to OAuth 2.0 for Jira to create issues based on received mail. Learn more

Expected Results

The incoming mail server configuration page shouldn't show the warnings as all incoming mailboxes are using OAuth2 authentication.

Note about this bug

The reason why this bug is occurring is because it incorrectly checks the authentication method of all mail servers configured in the Jira application (whether it's an incoming mail server or outgoing mail server), instead of only checking the incoming mail servers.
 

Workaround

This is just a harmless message that can be ignored if all Jira Incoming Mail Servers are already using Oauth 2.0.
