Reserved names¶
Configuration → Reserved Names (admins only) lists names that can't be
registered or used as alias, for example admin, abuse, postmaster or
support. A reserved name blocks the part before the @ on all domains.

- Create adds a single name.
- Delete removes a name.
- Import adds names from a text file.
- Export downloads all names as
reserved_names.txt.
Import format¶
A plain text file (up to 1 MB) with one name per line. Empty lines and lines
starting with # are ignored, names are converted to lowercase, and existing
names are skipped.
# Common role addresses
admin
hostmaster
webmaster
A curated list of about 570 common names is available at
contrib/reserved_names.txt.
Import it right after the initial setup.
Reserved names don't affect existing accounts or aliases.
