Does anyone know how I can fix this....
You obviously have a sme6.x server exposed to the Internet, therefore you have an insecure server.
Many security bug fixes have been applied to sme since then.
Please update immediately to sme7.3, and you will have a secure server as well as a much better server in regards to email & spam filtering etc.
Please read the upgrade notes (see FAQ & forum posts) and be aware of the gotchas before upgrading.
In particular uninstall all incompatible contribs and custom templates and user custom templates. It's all in the FAQ.
There is a technique to restore from one of your existing mounted drives (sme6 to a new install of sme7), that can save a lot of time doing backups, and still retain everything on the original disk, just in case.
sme7 is so much better in many many respects, and it is secure and being updated regularly.
There is no more support for or upgrades being released for sme 6.
