Error everytime I try sending an email

[jsmith81dev]

Hey there

Having awful problems trying to send emails, just updated to the latest Exim version and now every time I try and send an email it shows:

2026-06-09 22:32:44 H=localhost (hostname.example.com) [::1] temporarily rejected MAIL <[email protected]>: invalid "condition" value "AUTH_BLOCK_SENDER_SPOOFING"

Exim version 4.99.4 #2 built 09-Jun-2026 22:11:48

Is there anyway of sorting this out please?

Thanks so much.

Do you have some custom exim files ?, just updated 2 servers without any issues test them also with email

check path :
/usr/local/directadmin/custombuild/custom/exim/exim.conf
if yes remove it

mv /usr/local/directadmin/custombuild/custom/exim/exim.conf /usr/local/directadmin/custombuild/custom/exim/exim.conf.disabled

Then rebuilt the Exim and Exim config:

cd /usr/local/directadmin/custombuild
./build exim
./build exim_conf
systemctl restart exim

Thanks for that, it works of course

But I had a customisation so emails received doesnt show the exim version, is there a way of doing this so it doesnt come up with that error?

1. Patch exim.conf to match the current version
2. or, remove the line AUTH_BLOCK_SENDER_SPOOFING from files /etc/exim.variables.conf*

I don't guarantee the things will work for you since you have the custom exim.conf. But these are ways for a further investigation.
