Tonight when I wanted to access the VestaCP Panel of my HostUs VPS it had a 502 Bad Gateway Error in it.  Then after searching VestaCP Forum and following Skurudo's steps I accessed my VPS with SSH to try and restart VestaCP.  Before I did it, I took a directory of my VPS and found the following file in it that doesn't belong and I don't have an understanding for:

dead.letter

This is how it appeared in the directory:

-rw-r--r-- 1 root mail 16369 Jun 22 07:39 dead.letter

Is it possible to explain what it is?  I wasn't working on my VPS on 22 June. I also haven't installed mail on my VestaCP or VPS.  I only have a minimal installation of VestaCP with nginx+apache, DNS (named), fail2ban firewall, DB and remi.

I decided not to restart VestaCP until I understood what the file was about. Is it something I should worry about and how should I remove it?

I found this "temporary solution" by zazzybob at the link below - not quite sure what it really did except maybe the equivalent of quarantining the contents of dead.file?  My worry was that apparently the file grows.  Apparently the command below would stop it from growing.

Code: (Select All)

cat /dev/null > /var/tmp/dead.letter
