I am attempting to restore some mail for a user. Generally, we do this by restoring a backup to a temporary account, then export the data that the user is requesting. Then we import that into their account.

I've discovered an issue. If my exported file is too large, it will not import. It gives me no errors, it simply doesn't import. It says the import has started, but never actually does anything.

Somewhere between a few mb, and around 50mb, is the cut off. I don't.

Now, we have a test server, which i use for troubleshooting and testing new releases and whatnot. The import WORKS there. no matter what the file size.

This is ZCS 6.0.10, in both cases.

Any suggestions?
