Okay so I keep getting spam complaints from my host and I am not sending out these emails. And I have blocked port 25 on my VPS but somehow they keep sending out these spam emails. How can I stop this? Also I run a couple web proxys. Could they be sending out the spam emails with my proxys?
Would be helpful if we knew what OS you;re running so we can offer suggestions. If you;re on a *nix based os, try doing a: cat /var/log/formmail.log from a root prompt to see what you've got. edit: Also would be helpful if we knew which proxy and version of such you;re running.
I am running on CentOS release 5.3 (Final) and the proxy I am using is Glype version 1.1 (Latest) Ran cat /var/log/formmail.log and got: cat: /var/log/formmail.log: No such file or directory Code (markup):
I'm blocked from the site from the library and for some strange reason the Glype site doesn't allow proxies to connect but a quick google pulls up this: http://glype.com/forums/index.php?/topic/4743-spam-message-about Looking at the date and what I can see in google, there may be an issue. edit: one of the librarians tried to pull it up for me and got blocked as well. They're supposed to have unfiltered access. Going through a VPN tunnel on one of my servers gets time out errors. Sorry that I couldn;t help more.
got this when trying to view that link [#10343] We could not determine which topic you were attempting to view. Code (markup):
If it comes down to it, and if you think your blocking isn't working, maybe you could ask your provider to block port 25 from your IP address? We've had to do that on occasion for abusive customers.
As noted up above, that's already being done. Please remember that it's always a good idea to read the thread that you post in. I finally got though via google cache (that's now blocked at the library as well) and the link is worthless. Sorry about that. Try looking at your webserver's logs to see if there's a single IP address that sticks out. If you want to pm me with your login and root information, I could take a look. I'll be in and out all day though.
I think there's a misinterpretation here. I'm assuming port 25 was blocked from within the VPS but for some reason is not working. I'm suggesting that the OP asks the person who manages the outer container of the VPS (think dom0 in Xen terms) to block port 25 from the outer container itself.
I just wanted to be sure that when you block Port 25 you are are blocking this as an outgoing connection. In most cases, when people say they are blocking Port 25, they block that port on their server which results in the server being unable to accept incoming connections on this port. However, when someone sends an email FROM your server it will not necessarily use Port 25 to SEND the email so blocking Port 25 does not stop emails being sent out. You need to be sure that you are blocking connections from ANY port on your server from connecting to port 25 on an external server. Maybe that's what you meant, but I just wanted to be sure.
Okay well I asked my host about blocking port 25 from my IP and they said "This hypervisor (VMware) works different than Xen. I can't block port 25 from without the hypervisor. But you can disable port 25 in your iptables firewall." So how do I disable port 25 in my iptables firewall. (not to familiar with CentOS.)
if you dont know how to block 25/OUT (not IN, its simpler!) better block it with support request not with firewall
If its bothering them so much, back everything up and ask for an OS reset, then just throw your configs and files back on?
