Multiple domains can be assigned to a postoffice. You need to have at least one domain configured in order to have a valid email address.
The Domain properties page allows you to redirect a domain to another server. If you wish to relay all the mail destined for a domain, you can enter the alternate IP addresses here.
Domain is disabled
Stops email being sent to the domain.
Abuse Address
Enter the email address or select the mailbox for the abuse@domain email address.
Postmaster Address
Enter the email address or select the mailbox for the postmaster@domain email address.
Catchall Address
A catchall address will catch all emails for a domain that do not have a mapping to a mailbox. Select either an existing mailbox to send all the emails to, or enter the email address to send these emails to.
Act as Smart Host
Redirects all mail for the current domain to another mail server. This would be used if, for instance, the server was acting as a backup mail server for the domain. Specify a port number by adding a colon and port number after the IP address. e.g. 192.168.3.45:30. Do not enter the IP address of your MailEnable server, as it will create a message loop (the mail server will send to itself) and messages will finally end up in the Bad Mail directory.
Use the ‘Only relay email from authenticated users’ option in order only to relay email from users that have met the SMTP relay option criteria. This can be used if a domain is configured to send to a specific relay server (e.g. you might configure the aol.com domain to relay through to another server for your users, but don’t want anyone to send aol.com messages through your server).
Add blacklisted domains for the selected domain. Blacklisted domains are unable to send mail to this domain. The Domain properties blacklist checks the envelope sender of the email, which may be different to the email contents.
To deny a site for all domains, you are able to enter a mask.
eg: *.com.au
Domains
Remote hosts can be denied access to the system by adding them to the blacklist for a domain. This effectively denies a server the ability to send to the domain if the domain in a senders email address matches an item in the blacklist. For example, if you add the domain 'mailenable.com' to the blacklist for a domain, then the domain will not accept any emails from mailenable.com.
