Error when trying to start mailbox services:

Exception in thread "main" Keystore was tampered with, or password was incorrect


This problem comes up because the Java keystore is either changed, or not accessible. Regenerating the certificates creates a new keystore.

To do so, first move the old keystore:

mv /opt/zimbra/mailboxd/etc/keystore /root/keystore.old

Then re-generate certificates and restart the mailbox service:

/opt/zimbra/bin/zmcertmgr createca -new
/opt/zimbra/bin/zmcertmgr createcrt -new -days 3650
/opt/zimbra/bin/zmcertmgr deployca
/opt/zimbra/bin/zmcertmgr deploycrt self
/opt/zimbra/bin/zmcertmgr viewdeployedcrt

zmmailboxdctl restart
