Address Aliases
Setting up Address Aliases.
The Accounts Address Aliases… menu selection is used to open the Alias Editor. The Alias Editor makes it possible for you to create "fictitious" mailbox names for your accounts or mailing lists, which is extremely useful when you want multiple mailbox names resolved to a single user account or list. For example, if Frank@altn.com handled all billing inquiries to your domain, but you wanted to tell everyone to send them to Billing@altn.com, then you could create an Address Alias so that messages addressed to Billing@altn.com would actually go to Frank@altn.com. Or, if you were hosting multiple domains and wanted all messages addressed to the Postmaster (regardless of the domain) to go to a single user, then you could create the alias "Postmaster@*=Henry@altn.com".
Because a "Postmaster" must exist at each Internet mail site, MDaemon will check your defined aliases at program startup and issue a warning if you have failed to create such an alias.
Define a New Alias
Address alias
Enter the email address for which you wish to create an alias. Wildcards of "?" and "*" are acceptable.
Actual address
Select an account from the drop-down list or type a new address or mailing list into this space. This is the actual address that will receive the message when it is addressed to a corresponding alias.
Add
Click the Add button to register the account alias request. The contents of the Address Alias and Actual Address fields will be combined and placed in the Current Aliases window.
Current Aliases
This window contains all current Address Aliases that you have created.
Remove
Click this button to remove a selected entry from the Current Aliases list.
Up
Aliases are processed in the order in which they are listed. You can move an Alias to a higher position in the list by selecting it and then clicking this button.
Down
Aliases are processed in the order in which they are listed. You can move an Alias to a lower position in the list by selecting it and then clicking this button.
Alias Options
It's OK to relay mail for aliases that include foreign domains
Click this control if you want MDaemon to relay mail for Address Aliases regardless of your Relay Control settings.
Aliases are ignored if address matches an existing account or mailing list
Sometimes you may want to create an alias that will be applied to some addresses but not others when they match an existing account. For example: you could create an alias using a wildcard stating that "*@mycompany.com=me@mycompany.com" which would cause all messages containing "@mycompany.com" to go to "me@mycompany.com" even if the addresses matched existing accounts. But, with this control activated only addresses that didn't match an account would have that alias applied to them.
Fully qualified aliases (no wildcards) are allowed to be list members
Click this checkbox if you want to allow address aliases to be members of MDaemon mailing lists. Only actual accounts can be list members if this control is not enabled. Note: address aliases containing wildcards are not permitted to be list members even if this control is enabled.
Mail from 'Postmaster' alias requires an authenticated session
Click this checkbox to require messages claiming to be from one of your "postmaster@..." aliases to be authenticated before MDaemon will accept them. Spammers and hackers know that the "postmaster" account exists and may attempt to use that account to send mail through your system. This option will prevent them and other unauthorized users from being able to do so. This option is also available on the SMTP Authentication tab in Security Settings (Security IP Shielding/AUTH/…, or Ctrl+F8). Changing the setting here will be reflected there as well.
IP Shield honors aliases
Click this option if you want the IP Shield (Security IP Shielding…) to honor address aliases when checking domain/IP address shields. If IP Shield honors aliases is clicked, the IP Shield will translate an alias to the true account to which it points and thus honor it if it passes the shield. Without this option enabled, the IP Shield will treat each alias as if it is an address independent of the account that it represents. Thus, if an alias' IP address violates an IP Shield then the message will be refused. This option is mirrored on the IP Shield editor-changing the setting here will be reflected on that dialog.
Replicate aliases to LDAP address book
Click this check box if you want aliases to be replicated to the LDAP address book. Alias replication is necessary for the remote LDAP verification feature to work reliably, but if you are not using that feature then replicating aliases to the LDAP address book is unnecessary. If you are not using remote verification then you can safely disable this feature to save processing time.
Use recursive aliasing
Click this check box if you want to process aliases recursively. Any alias match causes the resulting value to be reprocessed back through the entire alias list-it is possible to nest aliases up to 10 levels deep. For example, you could set up something like this:
durge@example.com = frank@example.com
frank@example.com = x@x.com
x@x.com = dwimble@my-example.net
This is logically identical to the single alias:
durge@example.com = dwimble@my-example.net
It also means that:
frank@example.com = dwimble@my-example.net
