# Manage DB writes for: DATABASE_VIRTUAL

|
|
# A virtual alias may be any of `user@domain`, `user`, `@domain`.
|
|
# Recipients are local (internal services), hosted (managed accounts), remote (third-party MTA), or aliases themselves,
|
|
# An alias may redirect mail to one or more recipients. If a recipient is an alias Postfix will recursively resolve it.
|
|
#
|
|
# WARNING: Support for multiple and recursive recipients may not be well supported by this projects scripts/features.
|
|
# One of those features is Dovecot Quota support, which uses a naive workaround for supporting quota checks for inbound
|
|
# mail to an alias address.
