This is, oddly, not very easily found/well documented when you do
Google searches for 'cygwin cron sendmail'.
cron on cygwin installs a symlink to /usr/bin/cronlog as
/usr/sbin/sendmail on installation. This is a good thing. This
script creates a file named 'cron.log' in your home directory for any
cron command outputs. If you look at it, you'll notice many
sendmail-like headers in the file.
To have cron actually send emails, you need to set up
/usr/sbin/sendmail as a link (or a program) to something that actually
I'm using msmtp, but I'm guessing ssmtp will be similar.
1) Remove the link /usr/sbin/sendmail
2) Create a new shell script or link in its place
ln -s /usr/bin/msmtp /usr/sbin/sendmail
(Note - use a decent editor instead of cat ... Control-D)
I just installed 'msmtp' on a new install and ran 'msmtp-config'. If
/usr/sbin/sendmail does *not* exist (ie, you install msmpt *before*
cron) then it will create this link for you.
Once you do all this, edit your crontab and put an entry in it like this:
* * * * * date
And reload (if you didn't do a 'crontab -e' to edit)
It may take up to 2 minutes for cron to start doing stuff, as the
minute in runs it'll load in the new crontab and then the *following*
minute, it will run 'date' and should e-mail it to.
Once you start getting e-mails, just comment this line out or delete it.
