Hello,

I'd rather avoid storing or using passwords directly in setroubleshoot
but it's simple to add another option to setroubleshoot.conf which would
enforce using local 'sendmail' binary instead of smtp_host.

Please take a look at 
https://gitlab.com/setroubleshoot/setroubleshoot/-/merge_requests/15 
and let me know if this would be acceptable for you.

Thanks,

Petr
