SMTPSaveImportErrors instructs the Domino SMTP listener to save a copy of an inbound SMTP message for later analysis when its import into the Notes store fails.
Profile
Parameter | SMTPSaveImportErrors |
Component | Server (SMTP listener / mail conversion) |
Category | Mail / Router (diagnostics) |
Available since | 9.0.x (per KB0032184) |

Values | 0, 1, 2 |
Storage location | <notesdata>/IBM_TECHNICAL_SUPPORT/ |
Values per KB0032184
Value | Meaning |
0 | Disabled (default) – failed imports are not saved |
1 | Saves only the (partially) converted Notes form of the message |
2 | Additionally saves the RFC822 source file of the incoming message |
Description
When Domino cannot successfully ingest an inbound SMTP message into the Notes store — for example due to a broken MIME structure, invalid headers, encoding errors, truncated attachments, or conversion problems — it typically results in an error in the SMTP log and
log.nsf. Without further configuration, the problematic message is then lost, which makes root-cause analysis difficult.SMTPSaveImportErrors enables saving these failed messages:- Value 1 – Domino saves the (partially) converted Notes document for inspection.
- Value 2 – Additionally, the original RFC822 source is saved as a text file. This makes it possible to analyze the exact MIME/header content or send it to HCL Support.
The files are written to the Domino data directory under
IBM_TECHNICAL_SUPPORT/ — the standard directory for diagnostic artifacts.Examples
SMTPSaveImportErrors=2
Enable dynamically at runtime:
set config SMTPSaveImportErrors=2
(Domino accepts the value without a restart; after a reproduction run, check the
IBM_TECHNICAL_SUPPORT/ directory.)Deactivate:
set config SMTPSaveImportErrors=0
Notes
- Check the directory – On overloaded servers,
IBM_TECHNICAL_SUPPORT/can fill up quickly if defective mail keeps arriving (e.g. spam with broken MIMEs). After analysis, clean up old files.
- Privacy – The saved RFC822 sources contain the complete content of the affected messages, including attachments. Restrict access to the directory accordingly.
- Complement to logs – Useful complement to
SMTPDebug/SMTPDebugIO: while SMTPDebug shows how the message arrived, SMTPSaveImportErrors shows what Domino could not convert.
- HCL Support – For mail conversion problems, HCL often requests exactly these files (RFC822 source from
IBM_TECHNICAL_SUPPORT/) for reproduction.
- Not to be confused – This parameter has nothing to do with bounce/NDR functionality; it only saves messages whose Notes conversion failed.
