this is working fine, but introduces a sqlalchemy warning
when using config-import:
/app/mailu/schemas.py:822:
SAWarning: Identity map already had an identity for (...),
replacing it with newly flushed object.
Are there load operations occurring inside of an event handler
within the flush?
- yaml-import is now logged via schema.Logger
- iremoved relative imports - not used in other mailu modules
- removed develepment comments
- added Mailconfig.check method to check for duplicate domain names
- converted .format() to .format_map() where possible
- switched to yaml multiline dump for dkim_key
- converted dkim_key import from regex to string functions
- automatically unhide/unexclude explicitly specified attributes on dump
- use field order when loading to stabilize import
- fail when using 'hash_password' without 'password'
- fixed logging of dkim_key
- fixed pruning and deleting of lists
- modified error messages
- added debug flag and two verbosity levels
