Ativar modo Both (ambos, http+https) no Zimbra

1. Desativar ProxySSLUpstream

zmprov ms `zmhostname` zimbraReverseProxySSLToUpstreamEnabled FALSE

2. Reconfigurar Nginx

/opt/zimbra/libexec/zmproxyconfig -e -w -o -a 8080:80:8443:443 -x both -H `zmhostname`

3. Configurar Zimbra para rodar no modo Both

zmtlsctl both
zmprov ms `zmhostname` zimbraReverseProxyMailMode both
zmprov ms `zmhostname` zimbraMailMode both

4. Reiniciar o Zimbra

zmcontrol restart



Simples, rápido e caceteiro 😉

Ah... se preferir redirect, só trocar no item 3 de both para redirect
