Domain Pointers are designed to be exact duplicates of the domain they're created under. As such, you cannot edit many aspects of them.
However, if you wish to have the website data remain the same as the main domain, but be able to control email accounts, you can do it by creating the pointer as another full domain name, and then use symbolic links to link the website data to that of the main domain.
1) If the Domain Pointer exists, delete it.
2) Create the Domain Pointer as a full domain:
- User Level -> Domain Setup -> Add Another Domain -> domain=domainpointer.com
3) Link the data directory that of the main domain, requires ssh:
cd /home/username/domains/domainpointer.com/ mv public_html public_html.old ln -s ../maindomain.com/public_html ./public_html mv private_html private_html.old ln -s ../maindomain.com/private_html ./private_html chown -h username:username public_html private_html
If everything works, and there is no important data in the public_html.old and private_html.old, then you can delete those 2 unused directories.
You can now create email accounts for domainpointer.com, independantly from the main domain.
