Delays in mail syncronization for mailboxes hosted on a Plesk server

Plesk for Windows Plesk for Linux kb: technical

Applicable to:

  • Plesk for Linux
  • Plesk for Windows

Symptoms

  • Users may experience delayed or inconsistent email synchronization on mobile devices, particularly with the following email clients:

    • Gmail app on Android and iOS
    • Outlook app on iOS
    • Default Mail app on iOS

  • The issue manifests as:

    • Emails not appearing automatically on mobile devices
    • Manual refresh required to receive new emails
    • Lack of push notifications for new messages

Cause

The primary causes for this behavior are:

  1. Mobile app settings and limitations
  2. Battery optimization features on mobile devices
  3. App-specific sync intervals

Resolution

To improve email synchronization on mobile devices, try the following solutions:

For Gmail on Android

  1. Disable battery optimization for the Gmail app:

    • Go to Android Settings
    • Navigate to Apps > Gmail
    • Select "Battery"
    • Choose "Don't optimize"

  2. Adjust sync frequency in the Gmail app:

    • Open Gmail app
    • Tap the menu icon
    • Go to Settings > your email account
    • Tap on "Sync frequency"
    • Select the desired interval (minimum 15 minutes)
For Gmail on iOS

  1. Enable push notifications:

    • Go to iPhone Settings
    • Scroll down and tap "Gmail"
    • Ensure "Background App Refresh" is turned on
    • Enable all necessary notification options

  2. Consider using the default iOS Mail app instead, which tends to have fewer sync issues

For Outlook on iOS

  1. Check Outlook app settings:

    • Open Outlook app
    • Tap your account icon
    • Go to Settings > your email account
    • Ensure "Push" is selected for new email notifications

  2. If issues persist, consider using the default iOS Mail app as an alternative

For iOS Mail App

  1. Optimize mail settings:

    • Go to iPhone Settings
    • Scroll down and tap "Mail"
    • Tap "Accounts" and select your email account
    • Ensure "Mail" is toggled on
    • Go back to Mail settings and tap "Fetch New Data"
    • Select "Push" if available, or choose an appropriate fetch interval

  2. Disable Low Power Mode, as it can affect background app refresh

Note: Most mobile email clients have a minimum sync interval of 15 minutes to conserve battery life. For immediate notifications, manual refresh may still be necessary.

Additional Information

If sync issues persist after trying these solutions, consider contacting the respective app developers for further assistance.

To ensure the issues are not related to the Plesk server itself, please contact Plesk support as well.
