SOGo v5 was released on Aug 10, 2020 by the SOGo team (https://sogo.nu), and nightly build packages for v4 and v4 were removed permanently. All users must switch to v5 as soon as possible.

Upgrade SOGo On RHEL/CentOS

• Backup config files first:

mkdir -p /root/sogo-backup/{sogo,sysconfig}
cp /etc/sogo/* /root/sogo-backup/sogo/
cp /etc/sysconfig/sogo /root/sogo-backup/sysconfig/

bash /var/vmail/backup/backup_*sql.sh
bash /var/vmail/backup/backup_sogo.sh

    SOGoMailingMechanism = smtp;
    SOGoSMTPAuthenticationType = PLAIN;

    SOGoSieveServer = "sieve://127.0.0.1:4190/?tls=YES&tlsVerifyMode=allowInsecureLocalhost";
