Description

According to HCL product documentation:
This setting determines how often workstations can contact the server to see if new mail has arrived for the user. This setting overrides the user's selection in the Mail Setup dialog box. You can increase the mail polling interval if there are a large number of mail users on your server and you want to prevent frequent polling from affecting server performance.
With MinNewMailPoll, the server enforces a minimum interval between mail polls of the Notes clients. The value acts enforced server-side and overrides the Check for new mail every N minutes setting in the Notes client (location/mail setup). With very many mail users on a server, a higher value can noticeably reduce the server load, while too high a value worsens the perceived response time for new mails.

Example configuration

MinNewMailPoll=5

Notes & pitfalls

  • Value in minutes, not seconds.
  • Deliberately overrides the client setting — a user cannot configure themselves "below" this value.
  • Different mechanisms apply for IMAP/POP3 clients (e.g. POP3_Config_Update_Interval, IMAP idle).
  • Too high a value can cause noticeable delays in workflow applications.
