These are some really useful notes.ini variables, if you’re changing any SMTP settings in Domino (in particular if you’re setting up or changing a TLS connection).
(NOTE: links updated January 2022)
- SMTPClientDebug, SMTPDebug and SMTPDebugIO – Description and usage here
- SmtpSaveOutboundToFile – Description and usage here
- SMTPSaveImportErrors – Description and usage here
Every time I’ve needed these in the past I’ve ended up correlating this list or similar, thought it might be useful to have them together in once place!
Note you can set any of these by running:
set config notesinisettinghere
from the Domino Console so if you wanted to set up SMTP debug, running the following would give you verbose logging:-
- set config SMTPDebug=3
- set config SMTPDebugIO=3
- set config SMTPClientDebug=3
- set config SMTPSaveOutboundToFile=1
- set config SMTPImportErrors=1
Obviously these settings will produce a lot of logging, which will effect performance, only turn these on for a short period, during non-peak times.
Let us know if you’ve found this helpful!

Morgan says:
DEBUGROUTER=3 is another good one to use, since it lets you see the outbound SMTP activity.
Steven Vaughan says:
Thanks Morgan – that’s another good one.
Gary Young says:
So what are the settings to revert these to “normal”
Cormac McCarthy says:
Hi Gary,
Thanks for you reply. For all of these you just need to
set config settingname=0
and restart the router.
(or remove the notes.ini settings and restart Domino)
Thanks,
Cormac

Thanks for that – the debug info has been useful, but quickly filling my logs.
On a side note, the links to description and usage are now broken (uses old IBM references)
Interestingly I cannot find anything on these Parameters (eg SMTPClientDebug) on the HCL Documentation site … Where can I find this info now ?

Hi Gary,
Sure, the blog entry is 9 years old so I’m not surprised the links don’t work 🙂 Great to know it’s still helpful though.
You can search SMTP on https://support.hcltechsw.com/csm?id=kb_search and you’ll find everything you need.
The following two, are probably most helpful:
https://support.hcltechsw.com/csm?id=kb_article&sysparm_article=KB0032184

Thanks,
