I'm still a total newbie in Zimbra.
And now i have a question...
I have an dynamic IP so that I must use an Smtp Relay Server for outgoing emals.
But how/where can i enter the relay server?
If i open web-front (configuration->server->mta->mta-relay...)
and there enter a smtp-relay-server, then it tell me "not allowed..."

sorry for my bad english
