Bash doesn't recognize comp

Hello again, i'm having troubles with comp, i've already used it in another machine a few months ago but now i can't make it work.

When i execute the command comp in the console, my system doesn't recognize it as a bash command, and it says that maybe the program comp is in any of the following packages:
nmh
mailutils-mh

I donwloaded the packages (the one called nmh had an error with a .deb file) and the problem persists.

I think the main problem is that i need to donwload some packages but since the ones that apt recomends don't work well i was thinking in asking you guys to guide me.

Well thanks in advance as always

Best regards.

Leonardo.

Thank you very much alex, i installed the package and worked.

Best regards.
