Zimbra Troubleshooting

When Amavis,Antivirus,Cbpolicyd,opendkim,Or Any Other Services Not Running Do The Following Things:-

Services

To Enable Zimbra Services:-

zmprov ms `zmhostname` +zimbraServiceEnabled cbpolicyd
zmprov ms `zmhostname` +zimbraServiceEnabled stats
zmprov ms `zmhostname` +zimbraServiceEnabled archiving
zmprov ms `zmhostname` +zimbraServiceEnabled antivirus
zmprov ms `zmhostname` +zimbraServiceEnabled antispam
zmprov ms `zmhostname` +zimbraServiceEnabled amavis

To Disable Zimbra Services:-

zmprov ms `zmhostname` -zimbraServiceEnabled cbpolicyd
zmprov ms `zmhostname` -zimbraServiceEnabled stats
zmprov ms `zmhostname` -zimbraServiceEnabled archiving
zmprov ms `zmhostname` -zimbraServiceEnabled antivirus
zmprov ms `zmhostname` -zimbraServiceEnabled antispam
zmprov ms `zmhostname` -zimbraServiceEnabled amavis

These Are The Services Need To Be Running In Zimbra Mail Server:-

Troubleshoot

To Check File Permissions In Zimbra Mail Server :-

 /opt/zimbra/libexec/zmfixperms -e -v

To Enable IPv6 ::1 [It May Cause Failure IN Running Zimbra Service ]

vim /etc/sysctl.d/99-sysctl.conf

sysctl --load /etc/sysctl.d/99-sysctl.conf

vim /etc/default/grub

add the following line in configuration:-

GRUB_CMDLINE_LINUX="$GRUB_CMDLINE_LINUX ipv6.disable=1"

The next step is to update the GRUB CFG files. Type the following command to locate the grub files.

ls -lh /etc/grub*.cfg

You will see 2 GRUB CFG file paths: /boot/grub2/grub.cfg and /boot/efi/EFI/centos/grub.cfg.

Type the following command to create a new GRUB configuration file and save it to /boot/grub2/grub.cfg.

grub2-mkconfig -o /boot/grub2/grub.cfg

Next, type the following command to create a new GRUB configuration file and save it to /boot/efi/EFI/centos/grub.cfg.

grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg

Finally, reboot your CentOS 8 machine.

reboot

After rebooting, type the following command to verify whether IPv6 is disabled.

ip a | grep inet6

Instant IPv6 Enable Command:-

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=0

Instant IPv6 Disable:-

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1

Network Adapter Configuration:-

ip -6 addr

sudo su - zimbra -c "zmproxyctl stop"
sudo su - zimbra -c "zmmailboxdctl stop"

You’ll see a number of files.

cert.pem: The actual certificate file
chain.pem: The chain file
fullchain.pem: Concatenation of cert.pem + chain.pem
privkey.pem: Private key

sudo su - zimbra -c '/opt/zimbra/bin/zmcertmgr deploycrt comm /opt/zimbra/ssl/letsencrypt/cert.pem /opt/zimbra/ssl/letsencrypt/chain.pem'

sudo su - zimbra -c "zmcontrol restart"

SSL Old

Step 1: Secure Zimbra Mail Server with Let’s Encrypt SSL Certificate

Create directory that will hold Let’s Encrypt certificates for Zimbra Server.

sudo mkdir /opt/zimbra/ssl/letsencrypt

Copy Certificate files.

CERTPATH=/etc/letsencrypt/live/mail.linoxcloud.com
sudo cp  $CERTPATH/* /opt/zimbra/ssl/letsencrypt/

Confirm files are copied successfully.

$ ls /opt/zimbra/ssl/letsencrypt/
cert.pem  chain.pem  fullchain.pem  privkey.pem  README

We now need to build a proper Intermediate CA plus Root CA. You must to use the IdenTrust root Certificate and merge it after the chain.pem.

https://letsencrypt.org/certs/trustid-x3-root.pem.txt

cat $CERTPATH/chain.pem | sudo tee /opt/zimbra/ssl/letsencrypt/zimbra_chain.pem

View the file contents:

$ cat /opt/zimbra/ssl/letsencrypt/zimbra_chain.pem
