I'm using cPanel & WHM v102.0.8 (STANDARD) and CSF Firewall v14.16.
Today I changed some settings: SMTP_ALLOWUSER (added another user) and also added some ports to TCP_OUT list. Then I restarted the firewall and tested the new rules. Everything worked fine.

We are running an Elastix SIP phone server and we have been using CSF firewall for the past 7 years with no issues. We have employees that want to start using software based phones from their mobile devices (iPhone and Android phones) to access our company phone system while they are traveling outside of the office.
How can I allow mobile phones with dynamic IP's through CSF?
Hi,
I'm using Amazon Simple Email Service to send newsletters.
If I stop CSF all works fine. If CSF is on I cannot send the newsletter (connection refused 111).
I found this old topic:

Do you know hot to put in white list amazon service definitively?
Thank you very much
