We are experiencing a critical issue with the Email Communication feature in ERPNext. Recently, we discovered that e-mails sent to our ERPNext managed inbox are only partially being imported into the system. Some mails are not imported.
The Issue:
-
We were alerted by external parties asking why their e-mails went unanswered. But we never got those mentioned mails.
-
Upon checking our external Webmail inbox, the messages were present, but were missing from the same inbox within ERPNext
Through investigation, we determined that all incoming e-mails marked with the Priority “High” specifically those containing these header lines:
X-Priority: 1 (Highest)
X-MSMail-Priority: High
are not being imported into ERPNext. They do not appear in the Communication.
Technical Environment Details:
-
ERPNext Version: v15.78.0 (version-15)
-
Affected Feature: Email Communication / Mail Importer.
-
Affected Messages: Only e-mails with High Priority.
-
Email Protocol Used: IMAP
Troubleshooting Steps Taken:
-
Confirmed messages exist in the external Webmail client.
-
Searched ERPNext GitHub and forums for related bug reports, but found no similar issue.
Has anyone encountered this specific failure where the mail importer seems to be silently skipping high-priority e-mails? Any insight or potential solution for this critical data loss issue would be highly appreciated.
Thank you,
David
