Problem

Composing a new message causes an authentication window to appear

Solution

This comes up because the user's signature consists of an image that isn't publicly accessible.

Step 1

To fix this, first set the zimbraPublicHostname to a publicly accessible hostname :

zmprov md example.com zimbraPublicServiceHostname mail.example.com

Step 2

And then check the user's signature for any image that is accessed by an internal hostname :

zmprov gsig user@castlebranch.com

Step 3

If there is one, reattach the image so that the new value of zimbraPublicServiceHostname is picked up.
