[infrastructure] Fixing Zimbra accounts

[Ean Schuessler]

Hi all,

I've rearranged the way mail services are handled for the 
opensourceforamerica.org domain so that the main server now handles the 
messages instead of Brainfood's Zimbra server. Consequently, I now need 
to remove service for that domain from my server. Unfortunately, Zimbra 
doesn't appear to allow me to migrate these domains to another primary 
domain and will, therefore, need to delete them. I'm happy to reissue 
them as something like address at zimbra.opensourceforamerica.org and then 
set up aliases from the main server. If you have any mail on the OSA 
Zimbra server please let me know if you would like to remove it before I 
make my changes.

I will be traveling tomorrow and won't do anything until I've checked email.

Thanks,
Ean
