Title: amavisd.service failed with result protocol failed to start mail content checher
Post by: anandmys on June 24, 2026, 02:35:30 AM

Everything was running smooth.

But last 3 days, everyday, mails stop working.

I saw some error messages like

cwp amavisd.service failed with result 'protocol'
failed to start mail content checker

Most of the times, cant login to cwp admin

Restarting the server fixing the issue for few hours.

Please suggest

Anything to do with this issue?

Are you running stock CSF/LFD provided by CWP or the Aetherinox fork (I run the latter).

Can you make sure your system time is right? I usually use 0.pool.ntp.org and 1.pool.ntp.org for time servers.

The 0.pool.ntp.org address is part of the global NTP Pool project. It directs your system to a large, dynamic cluster of volunteer time servers, automatically assigning you the geographically closest available server to ensure high precision and minimum network delay

You may need to temporarily disable Amavis if it is the cause of your error. Try commenting out the relevant section in

Code: [Select]

/etc/postfix/master.cf and restart postfix.

Thank you. Where to look for and use these values for time servers?

Edit your chrony configuration to set the timeservers:

Code: [Select]

nano /etc/chrony.conf

Want me to take a look at your server? If so, PM me connection details.

Ouch! Looks to need some serious cleanup work, unless you can roll back a few days before the infection. See this thread for remediation techniques and scripts:
