Re: How-to Prevent external sender spoofing to EFA
The easiest best solution to prevent spoofing in a standard, simple environment is ADD BLACKLIST from @yourdomain to @yourdomain. If you handle multiple domains, add a BLACKLIST entry for each combination which should NEVER pass through your external SMTP gateway. Internally, all network equipment ...

Re: opendmarc.service failed - kills mailscanner?
its appear to be a brut force or something similar to manipulate EFA.
what firewall are you using in front of the EFA? what ports are open from the WAN to the EFA? are you using some kind of ids/IPS?

Re: Next Major Release OS Version Survey 2020
now the Centos 8 announcement, does mean anything for the efa project?
no patches will be available soon?
I think ubuntu or RH is a good OS.

Re: root password
I strongly suggest that you use ssh keys to allow access to your root account rather than setting a password. It'll also make the winscp and putty tools easier to use. Personally, I use a non admin account as my login using ssh keys, and then taking the second step of using sudo to make any changes...

Re: SPF Not working
i am wondering why are you using office 365 spf record to send out using your EFA? please provide more details if you need support. wihtout info/details/screenshot we wont be able to help. SPF records /IP are published ips which means you dont have to mask them, everyone on the internet can find them.
