set up a catch-all account to a domain name

[rafrio]

I'm trying to set up a catch-all account to a domain name via SOAP. I added an attribute called "zimbraMailCatchAllAddress" to the CreateDomainRequest, but it's not working. Below you can see the GetDomainResponse from SOAP:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
- <soap:Header>
- <context xmlns="urn:zimbra">
<sessionId type="admin" id="3022">3022</sessionId>
</context>
</soap:Header>
- <soap:Body>
- <GetDomainResponse xmlns="urn:zimbraAdmin">
- <domain name="somedomain.com" id="xxxxxxxxxxxxxx">
<a n="o">somedomain.com domain</a>
<a n="zimbraGalMaxResults">100</a>
<a n="objectClass">dcObject</a>
<a n="objectClass">organization</a>
<a n="objectClass">zimbraDomain</a>
<a n="zimbraDomainName">somedomain.com</a>
<a n="zimbraId">xxxxxxxxxxxxxx</a>
<a n="zimbraGalAutoCompleteLdapFilter">externalLdapAu toComplete</a>
<a n="zimbraGalInternalSearchBase">DOMAIN</a>
<a n="zimbraDomainType">local</a>
<a n="dc">somedomain</a>
<a n="zimbraMailStatus">enabled</a>
<a n="zimbraGalLdapAttrMap">zimbraMailCatchAllAddress =someaccount@somedomain.com</a>
</domain>
</GetDomainResponse>
</soap:Body>
</soap:Envelope>
