Hi there,
I have realized that the dead.letter under root directory is increasing due to an everyday rsnapshot message. I don't need such message because rsnapshot has its own logfile. I suspect these messages come from rsnpshot via vixie-cron. However, rsnapshot has no option to control these messages. Has anybody know to fix this?
Best

It's probably indeed from vixie-cron, vixie-cron should have a dependency on a mail system as that's the normal way for cron to notify output of cron jobs.
A way to "fix" this? redirect stdout and stderr to /dev/null in your crontab.

... but you could also set up the mail system so your system can warn you if something is going wrong, like smartctl, etc. Whether rsnapshot output is part of it is up tp you decide of course.

Probably got ssmtp installed with vixie-cron, as IIRC a mail transfer agent virtual is a dependency of vixie-cron.

Another idea is to use ssmtp to forward mails to another box if one really doesn't want a full mail system on the machine.

Full mail system really won't take much resources, but centralized mail makes sense, I'm using my router to receive all warnings from my LAN for instance.

rsnapshot seems to use v-cron via internals. I mean, there isn't a rsnapshot line in crontab to redirect to /dev/null or to anywhere.

That's exactly what is happening. SSMPT depends on virtual/mta-1 which is also a vixie-cron dependency.
Solutions was unmerge ssmtp since it's something I almost never use.
Thanks for helping.
