Masquerade all hosts under a domain

V8.8 and above

Ordinarily, masquerading transforms any host from a list of hosts in the class $=w ($=w) into the host defined by MASQUERADE_AS. If domains are also masqueraded with MASQUERADE_DOMAIN, they too are transformed. For example, consider these declarations:

 MASQUERADE_AS(`our.domain') MASQUERADE_DOMAIN(`her.domain') 

The first line causes any host part of an address contained in the class $=w to be transformed into our.domain . The second line transforms the domain part of her.domain into our.domain .

The key point here is that the domain part her.domain will be transformed, whereas hosts under that domain will not be transformed:

 [e-mail]   becomes   [e-mail] [e-mail]   remains   [e-mail] 

If you wish MASQUERADE_DOMAIN to transform all the hosts under the declared domain, you can use the masquerade_entire_domain feature:

 MASQUERADE_AS(`our.domain') MASQUERADE_DOMAIN(`her.domain') FEATURE(`masquerade_entire_domain') 

This feature extends masquerading of her.domain to include all the hosts under that domain:

 [e-mail]   becomes   [e-mail] [e-mail]   becomes   [e-mail] [e-mail]   becomes   [e-mail] 

Note that you can masquerade only domains that are under your direct jurisdiction and control . Also note that domain masquerading is intended for actual domains. Virtual domains are better handled with the genericstable feature (FEATURE(genericstable)).
