Hi!

When using podebconf-report-po with --postpone or --mutt and not having
libmail-box-perl installed, the program will let you write the mail but
then fail afterwards because it does not have the needed module
installed, w/o saving the written stuff. It would be nice if it could
fail earlier.

It also does not let you use --postpone or --mutt w/o having
libmail-sendmail-perl installed. It would be nice not needing them
if they are not needed to run the program.

thanks,
guillem
