Domain aliases not covered in the wiki

[srandall]

I have a situation where I have more than 100 domains aliased to 1 single domain entry. So in my Zimbra admin I have a list of several domains, and one of those actually has well over 100 aliases. For example: I have A.com, B.com and C.com. C.com has D-Z.com aliased. I accomplished this, the hard way, by entering something like
zmprov cd D.com zimbraDomainType alias zimbraMailCatchAllAddress @D.com zimbraMailCatchAllForwardingAddress @C.com
manually.
My question is basically this, "is there an easier way of managing domain aliases?" I also now have need for a mail box say "foo" on domain H.com. I can create this in C.com, however, I then have "foo@C-Z.com. I could also pull H.com out of the alias pool and create it as a stand alone domain with the "foo" mailbox ... (I actually need to have foo@H.com as an alias that points to foo@A.com)
I'm just hoping I've missed something and there is an easier way of managing these issues. I may have over/under thought this problem through. Any advice is greatly appreciated.
I like Zimbra, but could live with out ldap. Perhaps the question should be, "can I install Zimbra without ldap to function more similarly to my current postfix/cyrus solution?"
