relaying outgoing mails based on rules

[gberberoglu]

hello,

I'm working on a email gateway solution and investigating zimbra for collaboration.

Is it possible to create a rule / configure Zimbra to relay outgoing messages external SMTP server based on a tag?

assume that there is a zimlet that adds a special string to subject/body/header to tagthe message.. the use-case is, if user clicks the "tag message" button in zimlet, the mail will be relayed to our smtp directly..

thanks!

Could you please describe your actual use case ?
