Re: I dont receive or send mail after reboot Centos 7.6

Try this:

- Open file /etc/amavisd/amavisd.conf, find line below:

@bypass_virus_checks_maps = (0);

Replace "(0)" by "1" (without quotes), then restart Amavisd service.
- Put all emails in queue to HOLD:

postsuper -h ALL

- Kill all "clamscan" processes with command:

pkill -9 clamscan

- Start clamd service:

service clamd@amavisd restart

- Re-enable virus scanning in /etc/amavisd/amavisd.conf with setting below:

@bypass_virus_checks_maps = (0);

- Re-queue all hold message for delivery:

postsuper -H ALL

BTW, i fixes same issue for 2 clients in passed week, i guess there's something wrong with clamav or its virus signature database... it becomes more memory hungry.

Re: I dont receive or send mail after reboot Centos 7.6

UPDATE on this issue:

If server has 4GB or even less memory, ClamAV starts slowly and takes a long
time. It may exceed systemd default timeout setting and considered as failed
to start.
We need to increase the timeout value to avoid this issue. Steps:

*) Create new directory:

- on CentOS: /etc/systemd/system/clamd@amavisd.service.d/
- on Debian/Ubuntu: /etc/systemd/system/clamav-daemon.service.d/

*) Create file "override.conf" with content below under this new directory: 

[Service]
TimeoutSec = 600

*) Run "systemctl daemon-reload".

Re: I dont receive or send mail after reboot Centos 7.6

Thanks for posting this.  We had this issue on a Centos VM (w 8GB allocated) immediately after a rebooting for security updates this morning: 

Sep 19 06:39:23 m1 systemd: clamd@amavisd.service start operation timed out. Terminating.
Sep 19 06:39:23 m1 systemd: Failed to start clamd scanner (amavisd) daemon.

I haven't taken the time to poke around, but it's likely the latest version of the clamd daemon is taking a lot longer to start regardless of memory.

ClamAV 0.101.4/25577/Thu Sep 19 01:20:13 2019
CentOS Linux release 7.7.1908

Did you update /etc/systemd/system/clamd@amavisd.service.d/override.conf?
