I am running Fedora Core 5 (I know shame on me for being out of date) and sendmail 8.13.5. The question is hopefully simple and I will also give the command I was attempting after spending some time in the --help and man pages which are a bit confusing. I also have 4 domains that relay with my system.

Here is the command I tried but it doesn't seem to process just the requested.

sendmail -q -v R <user> or <domain>

I think the confusion for me is the R (assuming this is telling the system recipeint). I tried a -R but get the error "Invalid -R value."

Thanks for taking the time to assist!

Try 'sendmail -v -qR<full recipient email address>'? Dunno about domains though or if globbing would work.
