Re: Postfix Stalling
Hi Shawin,
i've noticed this last day too on one of our EFA. so i beleive it some kind of DDos or brute force.
i am working with Paul in order to configure fail2ban in order to provide some security.
lately we have a IDS in front of the EFA which keeps the logs clean.
EFA is working fine now

Re: Fail2ban
The first question is: can you see from your apache access logs, or error log or any log something that you could define as a brute force attack? If yes, then we can make a fail2ban rule to block the attempts. If not, then fail2ban won't help. If you can show me some examples errors, I can help you...

Re: Fail2ban
Sure. Assuming that there is a recognizable pattern in some log files, you can configure Fail2Ban to watch for it and block appropriately. The first question to ask yourself, is how do you know you are being brute forced? (i.e. does that show up in the log files in a recognizable pattern). Once you...

Re: Fail2ban
Hi Paul,
Our EFA has a https over the internet so the users on the go can release their emails.
so the https://efa.domain.com is open on the internet i want to include the fail2ban to block the brute force ip over the internet.
is this possible to configure with fail2ban ?

Re: Exchange Server 2016 replay to EFA for out going Emails
We have the same configuration up and running
on the your Exchange you need to configure it to send using smarthost, the smarthost is going to be your EFA IP/FQDN.
note: please make sure your Exchange IP is on the EFA whitelist configured.
