Yes, sendmail.sendmail is the mta on my system too.

I see no sendmail error after I remove the r2e entryl from the crontab. 
rss2email should not be using sendmail.

I start getting sendmail and crond entries as soon as I add r2e to the 
crontab. I see that one crond entry is made every time a cronjob is run.

Now that being solved. I have to look why I have numerous "fedora rngd[878]: 
read error" entries.
