Q: How can I upgrade from old version of Open Webmail?
A: Each version of openwebmail is made to be backward compatible with
old ones, no user setting or mail message will be lost after upgrade.
The upgrade steps:
1. make a copy of your old openwebmail.conf
2. install new openwebmail in the same location as old version
3. update the new openwebmail.conf with the setting in old one.
