Relay for multiple domains

[mrdebian]

Hi all,

I've got around 20 domains on different mail servers (postfix, exchange, gmail etc) and want to forward all of them into a local Zimbra email server (with dyndns dynamic domain) in order to give my users sharing options for calendar & contacts. Users must be able to send email through Zimbra by using each of the domains SMTP.

Is there a way to handle this scenario?

I've read about relay in the Wiki but it contains information only for single smtp/domain.

Any help is much appreciated.

Cheers

I've read about relay in the Wiki but it contains information only for single smtp/domain.

DId you search the forums, there's several threads and a wiki article on the subject (Transport Tables): site:zimbra.com +relay +"multiple domains" - Yahoo! Search Results

I forgot to mention that all emails need to be stored in the original email servers and just forward a copy of them to the Zimbra.

I read already the wiki pages about the smtp authentication and transport tables, I just can't find anywhere if I can store the emails to the original servers and just send a copy to Zimbra.

Any help other than link to yahoo search will be much appreciated.
