True. But you can control your data flow.

Add this to your firewall:

iptables -A OUTPU -p tcp -m state --state NEW -m recent --set

iptables -A OUTPUT -p tcp -m state --state NEW  --destination-port 25 -m recent --update --seconds 60 --hitcount 3 -j DROP

This means that all the connections made from your VPS to the internet will be throttled to 3/minute. All the rest will be droped. This way, your VPS won't be flagged on our system.

Due to abuse on our network to send spam, since 25-02-2012 we do not allow the direct email sending through our servers. This means that to be able to send emails, you'll need to setup a relay server.

To use the relay server, you don't have to place a username or password. The server is protected by IP address.

Always use "relay.lusovps.com" because of redundancy.


Sendmail

To use a relay server on sendmail

vi /etc/mail/sendmail.cf

Find the word "DS"

/DS

replace with

DSrelay.lusovps.com


PostFix

To use a relay server on postfix

vi /etc/postfix/main.cf

Find the word "relay ="

/relay\ =

replace with

relay = relay.lusovps.com

True. But you can control your data flow.

Add this to your firewall:

iptables -A OUTPU -p tcp -m state --state NEW -m recent --set iptables -A OUTPUT -p tcp -m state --state NEW --destination-port 25 -m recent --update --seconds 60 --hitcount 3 -j DROP

This means that all the connections made from your VPS to the internet will be throttled to 3/minute. All the rest will be droped. This way, your VPS won't be flagged on our system.
