Having a problem with my new zimbra setup. Whenever I reply to a message, the "Account" field has two options: the first has the name of my main (and only) account but no email address after it, and the second says Primary Account and is followed by the correct email address.

If I don't manually choose the Primary Account every time, the send fails and comes back with a null sender error. I only have once account so I don't know why I have two options at all, and further, why only one of them works, and why the broken one is the default selection.

Thanks for any help!!
