Me too. Countries like China, Russia, etc. attack my servers constantly.

well it should be possible to block certain countries from accessing certain ports - for example mail ports ... to prevent password cracking attempts.

this feature is more important today than ever. i don't really understand why so few votes were made for it. :(

plesk is one of the best applications i used in my live. so you have to go forward.

This is a very important feature as people try and ***** SMTP passwords and even if paying for Imunify360 that doesnt help because each attempt comes from a new password. If you know which geographical location most of your users are from then we should be able to block IMAP/SMTP access from all countries and only allow certain countries. This works well in Juggernaut but seeing that I pay so much more from Imunify360 I would expect this to be standard in Imunify360

Have the same problem

Maintaining lists of IPs or even subnets by hand on multiple servers is neither practical nor secure enough. There are already projects that maintain such lists (honeypot, ip2location etc).

I have enabled fail2ban and greylisting but I still frequently see servers in the mail.log which try to login with dictionary passwords.
The only way I know to get rid of those is to deny them completely.
It is a pain to do this from the GUI and there should be a CLI for this.

The Plesk firewall already can blocks of networks, by adding a CDIR netmask.

In your example, use 5.10.0.0/16 to block all traffic from the 2.10 network.
However, this does not block data from a specific country, but from a specific (group of) network(s). Keep in mind that countries may have a lot of A/B/C type of networks that are not consecutively ordered.

I don't know any complete list of networks used in a specific country, but you can do a search at organisations like ripe.net, apnic.net, afriinc.net and arin.net to do research for networks.

This and clamav should significantly improve server safety

Just use this script: https://github.com/trick77/ipset-blacklist

Hi there.
Would be a verny "nice to have". I really hope the guys at Plesk get around to this this year ! ! !

maybe everyone will block russian traffic, so sensitive for plesk owners,

it will be very appreciated !

It would be very appreciated!
We can all save bandwidth.

Hey Adam, try to set you SPF with -all (minus sign). And make you sure to have only sender server IP or service included on your spf.

PLEASE get country IP blocking or bulk IP blocking abilities. At times I am getting up to 45,000 spoofed emails (spoofed from my own account) a day. SPF records and DKIM settings just don't work!

I have a lot of spam from .ru and never need to get .ru emails so I would love to be able to block them. Our business is Australian based.

This feature is free at cpanel. why plesk is not doing this.??

Wow! 5 years and nobody at Plesk thought to implement this feature. From a paid panel I expected more...
