Subdomain Definitions


This feature lets you define multiple subdomains for any existing domain on the mail server. The advantage of this feature is that the original domain (eg. in Recipient field) is always preserved. This might be useful when subdomains for specific domain are defined on a remote server and the mail server is just supposed to forward all mails for any of these subdomains to that server - see note (2) at the end of this file for more details.

Formal Syntax:

items = 1*(item CRLF)  
item = subdomain "=" domain  
subdomain = (domainmask / domain)  
 

Example:

sales.merak.com=merak.com
info.merak.com=merak.com
*.icewarp.com=icewarp.com
 

Notes:


(1) This means that mails going to sales.merak.com or to info.merak.com domain will be delivered to merak.com (this domain must be defined on the server). All mails going to whichever subdomain of icewarp.com will be delivered to the icewarp.com domain (this one must be also defined on the server).
(2) In case icewarp.com domain were defined as a backup domain, the messages going to this domain (ie. also messages going to any icewarp.com subdomain) would be forwarded to the remote backup mail server with proper subdomain name preserved in Recipient field.
