Stop cron daemon "symmetrical.xm" error messages in Terminal mail

Also, when I userun $ crontab -e, this is what is shownreturned:

I'd really appreciate it if someone could help me understand how this started and what I can do to stop it from happening (or if I should stop it from happening at all). I've read somewhere that deleting the MyUsername file at /var/mail/ would stop these emails from coming in but I really wantam trying to knowfigure out why the Cron Daemon is sending me these error messages in. To clarify, I would not like to suppress mail from cron altogether; so, I don't want to

Delete the MyUsername file at /var/mail/, OR

Change the MAILTO variable in /etc/crontab to MAILTO="" (as suggested in this link)

Instead, I'd be really grateful it if someone could help me understand

How/why this started happening

What I can do to stop it from happening again (or if I should stop it from happening at all)

Which app/script requires the missing file/directory called symmetrical.xm and why

Any other additional information to add to the first placepoints listed above would also be greatly appreciated.

Stop cron daemon error messages in Terminal mail

After upgrading to High Sierra (I think) I've started receiving the following message almost every time I start up Terminal:

You have new mail in /var/mail/MyUsername

I had some problems upgrading to High Sierra so I strongly suspect this started after the upgrade, but cannot be absolutely certain.

When I enter the $ mail command and read the messages (which can amount to hundreds at one go) this is what is written:

Message 1:
From [email protected]  Tue Nov 28 21:37:04 2017
X-Original-To: MyUsername

/bin/sh: /Users/MyUsername/Library/symmetrical.xm/symmetrical.xm: No such file or directory

Also, when I use $ crontab -e, this is what is shown:

37 * * * * /Users/MyUsername/Library/symmetrical.xm/symmetrical.xm cr
~

"/tmp/crontab.SsevmMDt1o" 1L, 72C

I'd really appreciate it if someone could help me understand how this started and what I can do to stop it from happening (or if I should stop it from happening at all). I've read somewhere that deleting the MyUsername file at /var/mail/ would stop these emails from coming in but I really want to know why the Cron Daemon is sending me these error messages in the first place.

Thank you!
