Known Issues, Limitations, and Alternatives

Process Naming Specification​

The name of the process you specify while designing it using Process Designer or IntelliAppZ Designer should adhere to certain specifications. You can find those specifications over here.

Length Specification​

  • The Name cannot exceed 98 characters.

  • UNC format is followed in the case either the Nuget package or the corresponding IntelliAppZ MSI exceeds 259 characters. According to this format specification, we will prefix the path containing more than 259 characters with \?.

Special Character Limitations​

A process name must consist of letters, numbers, spaces, dots ".", underscores "_" and hyphens "-", must not begin with any special character except an underscore "_", and must not contain consecutive special characters, except for consecutive underscores "__".

Limitations and Considerations for POP3 Email Server Connections​

When configuring Email Triggers with POP3 as the selected Server Type, be aware of the following protocol-specific limitations:

  1. Email Retrieval Limit per Session

    • POP3 restricts the number of emails retrieved in a single session.
    • For example, Gmail’s POP3 implementation limits email downloads to a maximum of 250 conversation per session.

  2. No Real-Time Notifications

    • POP3 does not support real-time push notifications for new emails.
    • Email triggers using POP3 rely on periodic polling, which may introduce processing delays.

  3. Limited Filtering Capabilities

    • POP3 does not support server-side filtering.
    • All emails are retrieved during polling, requiring additional processing to filter messages based on subject, sender, or other criteria.

  4. Single-Access Nature

    • By default, POP3 downloads emails and removes them from the server (unless configured otherwise).
    • This behavior may impact email availability for subsequent triggers or access via other email clients.

  1. Use IMAP Instead (Preferred Solution)

    • IMAP offers real-time notifications, advanced filtering, and maintains the read/unread status of emails.
    • It allows selective email retrieval, reducing unnecessary processing.
    • Avoids the 250-conversation cap.

  2. Adjust Polling Intervals for POP3

    • If using POP3, configure an appropriate Message Polling Interval to balance timely email retrieval and server performance.

  3. Modify Email Server Settings

    • If retention is required, enable the Leave a copy on the server option in the Gmail provider’s POP3 settings.

      • Go to Settings > Forwarding and POP/IMAP > POP Download
      • Select: Keep Gmail's copy in the Inbox

    • This lets emails stay on the server for multiple downloads, but still doesn’t help with the 250 email-conversations limit per session.

By considering these limitations and recommendations, you can optimize IntelliBuddies® Email Triggers for reliable and efficient processing.
