Can you please tell us the subject / date you used? I do not see it in 
our archive, but I may use the wrong search criteria.
(Note that we are searching in an archive of 70000 messages from/to 
CRAN/CRAN-submissions produced only in 2022, i.e. > 300 mail messages a 
day.)

Best,
Uwe

Given the total lack of details I wouldn't expect any further answer here unless you can provide those.
