Issue Unknown Cron Job Sending Undeliverable Mail Every 1 Minute???

MojoJojo

New Pleskian
Hi,

I m totally new here. I have roundcube installed in plesk and after installing an ssl certificate then adding it to the webmail account, I noticed in one of the mail user accounts that there were a ton of undelivered emails. This is what they all say:

"This is the mail system at host stock.ovh.

I have no idea how to stop them from coming in aside from removing the user, however I believe that the cron job will just continue executing in the background because I removed the user, added the user back, and they just kept coming in every 1 minute.

I have scoured the internet but am not sure of the terminology to use, so I have found nothing to help me.

Any assistance will be greatly appreciated and remember I am totally new at all of this so you may.....no, you WILL need to really dumb down the solution for me :)

Thanks in advance!

Courtney
 
do you have any cron under this domain ? Can you check that

# crontab -l -u user

replace user with ftp username of the above domain
