Getting DDOSSED via Server IP - How to hide IP in notification email headers etc?

[g00gl3r]

I've disabled any uploading for newer usergroups. Only established members have the option now.

I'll need to get my head around this SMTP and see what leaves the IP in the headers.

Any SMTP relay server should hide your server IP, I have no experience with Google Apps though. I tried Gmail SMTP service a long time ago and my account got blocked in no-time.

Do you mean when we link to an image and then allow remote hosting of it?
Does that need removing?
