We are migrating to a new domain and the old domain as an alias domain for a period. For example, @newdomain is the main domain, and @olddomain is the old domain as an alias.
I have successfully change to the new domain (newdomain.com) and create the alias for the domain (olddomain.com).
Now, I used one new email account (firstname.lastname@example.org) in the new domain to act as announcement. With the attribute of zimbraMailCatchAllAddress in the account, I capture all the email in old domain, and I wanted to do the auto reply for all the user that send email to this old domain.com, to inform them regarding the newdomain.com
Now, with this setting, I could get the email forward to the newdomain.com and also capture one copy in email@example.com. But, with the setup of auto reply in this email account doesn't work.
It seems like it doesn't work if the email is not send to the firstname.lastname@example.org itself. Because when I send an email to email@example.com, the auto-reply is worked.
Please advice me. Thank you.
