Server constantly blocked by Barracuda Central

[samuelmf]

My server (Centos with WHM) doesn't have a email traffic
when i see the mail relayers i had 10 sent emails from one domain and 1000 from the root (CSF Emails) i dont see suspect emails
The email queue is in 0 emails

I have request many removals to barracuda central but my server ip is constantly blocked by them.

Someone could help me with that?

Hello ,

Have you checked your mail logs ? May be your one of the domain is sending mail through php scripts and due to that your mail server IP was blocked on barracuda.

My friend, thanks for reply, i've checked the exim log and all the mail activity is from localhost (CSF)
I performed the comand:
grep cwd /var/log/exim_mainlog|grep -v /var/spool|awk -F"cwd=" '{print $2}'|awk '{print $1}'|sort|uniq -c|sort -n

To view the scripts that send spam and the result is this
2 /usr/local/cpanel/whostmgr/docroot
4 /home/mydomain/public_html/web
7 /root
20 /
2862 /etc/csf

Hello

Are you able to obtain more information about why your server was blocked? Does the blocked report provide any additional details upon request?

Thank you.

 

[samuelmf]

No my friend, Barracuda Central does not provide info about why my server is being blocked.
All the security tips on the link are already set
