Yes, I have already months ago: 1.- To 15,000 IPs 2.- SMTP_AUTH = 1 I have a really good RBL that I checked a lot of times vs attacker IP's and my client IP's and it's 99% exact with the attacker IP's, so, yes a RBL will work if there's a way to block the SMTP AUTH using it.

Yep, I have them to 1 months ago, we don't have many clients, so in any false/positive is best for us to block all the wrong tries. But like I wrote, the have a LOT of IP's, it's a directed attack as they know the usernames, so is not kind of a "wide" attack, if we had the possibility to use...

Could be good idea, can you tell me how to disable SMTP AUTH on 25? Hmm it's spam? does this does what I'm looking for? I´m happy with Juggernauth, just lacking of this protection that could be useful.

Yeah I have added it, but the attacker really have lots and lots of IP's so no matter any range they have new ones :(

Thanks Peter, Yeah, would be great to accomplish this, I tried using Postfix main.cf, with these options added: smtpd_client_restrictions = permit_mynetworks, reject_rbl_client XXXX.XXX (RBL list) smtpd_delay_reject = no But at the end, it blocked all the attempts, not based on RBL

Hi again Peter, now they are trying with different usernames, but common ones, for example test@.. admin@.. we don't have any of these email addresses, it's possible to block instead the domain, the user "string"? I already tried changing the domain to the user strings, but they still can try...

Just to say Thank You again! It worked! After years of this, you save me =)

Thanks!!

Anyone?

Hi all, I have a kind of annoying problem, in the past, my main server IP belong to a very known domain website, they move their website/email server to a new IP range and I got their IP assigned (didn't know about this when I received them). I have more than 500 daily attempts to login with a...
