Product(s) Affected:

  • BlackBerry Internet Service
  • BlackBerry Internet Service

When attempting to integrate a Post Office Protocol (POP) email account into the BlackBerry Internet Service, the email account is integrated using Internet Message Access Protocol (IMAP).


This behavior is by design. The BlackBerry Internet Service will attempt authentication with the following preference:

  1. IMAP with SSL (Port 993)
  2. POP with SSL (Port 995)
  3. IMAP without SSL (Port 143)
  4. POP without SSL (Port 110)

When authentication is successful the BlackBerry Internet Service is configured using the highest available preference. 


It is always recommended to use IMAP over POP. However, if it is required to use POP instead of IMAP the following options are available:

  1. Stop the IMAP service. If the IMAP service is stopped the BlackBerry Internet Service will fail to connect to IMAP and default to POP. Only the mail server administrator can stop the IMAP service. 
  2. Block the IP addresses listed in KB11036 from accessing IMAP. This will block the BlackBerry Internet service from connecting to IMAP and force integration using POP. 

Note: If an email application is used, verify the settings to see if the POP server has a different server name. If the email application is set up with a POP server name (for example, instead of the original server name (for example,, try to perform an advanced integration using the POP server name. To perform an advanced integration, please refer to KB10154.
