[OPLINTECH] OPLIN e-mail failure

[Karl Jendretzky]

Everything besides the Zimbra server is running properly.

The Zimbra server was running Ubuntu 10, which is reaching end of life and
needed updated. The server was pushed to Ubuntu 14, and a patch was run on
Zimbra to bring it up to date, but after the patching finished the 80GB
LDAP database was corrupted. Attempts to fix the corrupted database failed.
Backups were restored, and a small patch was attempted to bring it up to
U14, but once again there were LDAP issues. A new Ubuntu 10 mail server was
built, and the exact version of Zimbra for the backups was installed, and
the backup data was put in place, but failed. Each step was slightly
different errors.

My thought is that the Zimbra server went through many updates through it's
life, and at some point some of the data went out of spec just enough that
it could only ever run on the exact U10 environment that it had. That U10
environment no longer exists.

Zimbra is a nasty beast. It uses many packages, but none are the repository
default packages. All are bundled with Zimbra, and all work just the way
Zimbra wants them to, meaning that support resources are sparse.

The only thing that the Zimbra server was doing was personal email accounts.
