Creating a Domain Alias

If you have a domain domain.com and you want the domain example.com to be an alias for it, so that sending mail to user@example.com is the same as sending mail to user@domain.com (delivered to the same mailbox), you can designate example.com as a domain alias when creating the domain. This example assumes domain.com already exists, but example.com does not.

zmprov cd example.com zimbraDomainType alias zimbraMailCatchAllAddress @example.com zimbraMailCatchAllForwardingAddress @domain.com

Relaying/Domain Forwarding

If you want the Zimbra server to relay all mail destined for a particular domain (say, example.com) to another mta (say, other-mta.domain.com), you can forward the domain.

zmprov
md example.com zimbraMailCatchAllAddress @example.com
md example.com zimbraMailCatchAllForwardingAddress @example.com 
md example.com zimbraMailTransport smtp:other-mta.domain.com

I think you can also do this as another way to make a sort of local domain alias:

zmprov
md example.com zimbraMailCatchAllAddress @example.com
md example.com zimbraMailCatchAllForwardingAddress @domain.com 
md example.com zimbraMailTransport lmtp:zimbra.domain.com

For non-zimbra domains, this might prove useful as well: Transport_Table_for_external_servers

Domain Catchall

If you want to set up an account "user@domain.com" to catch any mail not delivered to existing users in the domain "domain.com", you can configure the account as a domain catchall.

su - zimbra
zmprov modifyAccount user@domain.com zimbraMailCatchAllAddress @domain.com

If the users "john@domain.com", "webmaster@domain.com", and "xyznobody@domain.com" don't exist, and mail arrives for them, it will be delivered to the catchall account "user@domain.com". This will increase the amount of spam delivered, and can lead to being blacklisted. To remove the catchall from an email account, unset the catchall address:

zmprov modifyAccount user@domain.com zimbraMailCatchallAddress ""

Domain Masquerading

If you want mail from user@domain.com or user@zimbra.domain.com to appear to come from user@example.com, you can set the canonical address for the entire domain.

zmprov md domain.com zimbraMailCatchAllAddress @domain.com zimbraMailCatchAllCanonicalAddress @example.com
zmprov md zimbra.domain.com zimbraMailCatchAllAddress @zimbra.domain.com zimbraMailCatchAllCanonicalAddress @example.com

Additional

5.0.12+ allows some additional mapping of real to alias in order to:

A) Allow auth with alias domain addresses.

B) Send out-of-office notifications for alias domains.

zmprov md aliasdomain.com zimbraDomainAliasTargetId {zimbraId-realdomain.com}


5.0.16+ added the ability to do this in one command:

zmprov createAliasDomain(cad) {alias-domain-name} {local-domain-name|id} [attr1 value1 [attr2 value2...]]
