I'm interested in how you configured the backup server.
Do you just forward at the domain level or do you have all the account, aliases and distribution lists defined on the backup server (with appropriate forwards to the main server)?
If you are just forwarding at the domain level, how do you handle spam sent to invalid addresses?
On the main server, emails to invalid addresses are rejected at the 'envelope' stage of the SMTP transaction but a backup server will forward all emails to the main server and, for emails to invalid addresses, it will generate a rejected email which in most cases will bounce back to the
admin@domain.com address.
Is there some way to configure Zimbra on a backup server to check the email address on the primary server before accepting the email?
