Original GitHub issue: https://github.com/modoboa/modoboa/issues/2432

Impacted versions

OS Type: Debian
OS Version: 11
Database Type: MySQL
Database version: *
Modoboa: 2.0.0b3
installer used: Yes
Webserver: Nginx

Steps to reproduce

When installing beta to be able to work with 3.9.2 which is default in debian 11 the /webmail/ route throws an error on initial load.
With debug = True it shows a problem with the imap4-utf-7 encoding/decoding (after fiddling with unitialized data var in getquota function of imaputils.py first ;) )

Current behavior

Call of route /webmail/ fails

Expected behavior

With Python 3.9 the naming convention was changed back to standard.
In imap_utf7.py the hyphens in corresponding functions should be replaced with underscores.

see also: https://twistedmatrix.com/trac/ticket/9832 and https://bugs.python.org/issue37751
Naming convention should be adopted to PY3.9 naming convention.
