Looking for other way to look at spamming issue on a vps hosted server we DO NOT use as mail server.
We simply us it to host sites we build/maintain, and DNS manager that points MX records to our in-house mail servers.

Seems in that VPS hosted web server there are emails in the queue, cleared once already, passwords changed for user it looked like on the VPS account that was sending the mail.  But again queue is filled up.  I confirmed the mail is not coming from our internal emails servers via my FW and email server logs analysis and monitoring.

What can I possibly be missing as the VPS tech support is email only and nothings seems to be being done.  Thank you.

you say it has mail in the queue.. So you have the smtp components installed on the server and the web sites can send mail?

First thing, immediately change all passwords on that system and enable two-factor authentication if possible.

Then.  Should that system be sending email at all?  If not, ...

Is the offending system linux or Windows? If it's linux, disable mail / postfix / dovecot and block outgoing port 25 using iptables.

Long term fix:  Reload the system from known clean distribution kits and generate all new randomly generated passwords of at least 16 length.

Then the email components should be disabled or removed, and the problem will be solved.
