Ol\u00e1 ! Recentemente efetuei uma migra\u00e7\u00e3o de um Zimbra Network para Cloud e no ambiente n\u00e3o seria configurado um DNS local, utilizando somente o DNS de cache implementado pela pr\u00f3pria solu\u00e7\u00e3o.<\/p>\n
Neste cen\u00e1rio, o servidor possui um endere\u00e7o IP interno configurado, portanto, \u00e9 utilizado NAT para que o mesmo seja acessado atrav\u00e9s da Internet. Para exemplificar, vamos assumir as seguintes informa\u00e7\u00f5es:<\/p>\n
Dom\u00ednio: zimbra.local<\/p>\n
IP interno: 192.168.1.1<\/p>\n
IP v\u00e1lido: 1.1.1.1<\/p>\n
Hostname (interno e externo): mail.zimbra.local<\/p><\/blockquote>\n
O que precisamos corrigir neste cen\u00e1rio?<\/strong><\/p>\n
O Zimbra efetua as entregas das mensagens locais via LTMP, e como pode ser observado atrav\u00e9s do par\u00e2metro\u00a0zimbraMailTransport<\/strong>, \u00e9 utilizado o nome do servidor. Por padr\u00e3o, o LMTP ir\u00e1 efetuar resolu\u00e7\u00f5es DNS para a entrega das mensagens, portanto, o hostname mail.zimbra.local ir\u00e1 resolver para o IP v\u00e1lido, e pode ocorrer que o ambiente n\u00e3o permita esse acesso.<\/p>\n
Como devemos corrigir a entrega LMTP para utilizar o endere\u00e7o IP interno?<\/strong><\/p>\n
Para que ao entregar as mensagens locais, \u00e9 preciso informar ao Zimbra que o protocolo\u00a0LMTP<\/strong>\u00a0n\u00e3o deve utilizar DNS, e sim resolu\u00e7\u00e3o interna.<\/p>\n
Para isso, al\u00e9m de definir corretamente a entrada no\u00a0\/etc\/hosts<\/strong>, precisamaos definir\u00a0o par\u00e2metro\u00a0zimbraMtaLmtpHostLookup<\/strong>\u00a0conforme abaixo:<\/p>\n
zmprov ms `zmhostname` zimbraMtaLmtpHostLookup native<\/p>\n
zmprov mcf zimbraMtaLmtpHostLookup native<\/p><\/blockquote>\n
Ap\u00f3s as altera\u00e7\u00f5es serem efetuadas, N\u00c3O \u00e9 necess\u00e1rio reiniciar\u00a0nenhum servi\u00e7o.<\/p>\n","protected":false},"excerpt":{"rendered":"
