Postfix all mails Reject - GreyList Off !

Post by TFNcap »

Hi
I updated webmin (no problem)
then 260 yum update came (no problem)
Then he asked me to restart and
Now all posts are postfix reject

I was not using the gray list
I opened it but it doesn't leave greylist mails for hours

I want to close the gray list, but all incoming emails are postfix reject

i really need help

That error means you have some type of DNS or connectivity problem. can you ping 8.8.8.8? if so can you ping google.com?

your comment inspired me and the problem was solved

DNS settings deleted after updating webmin

webmin in dns review after review
I saw that the DNS line is empty
and I filled
solved

thanks for guiding me

God bless you :pray:

its seems you can ping ip but not fqdn
mostely is dns,

check if you have dns server installed/configured.
PS: make sure to disable ipv6
