Time zone setup at mailbox level
Each mailbox now has its own time zone setting.
The mailbox-level time zone, if set, will override the account-level time zone, which defaults to UTC. If this setting is not set, then the timezone will fall back to your own account-level time zone setting.
This setting is especially useful for delivery companies that are operating across different time zones and want to keep delivering on time across all their locations, without creating multiple Parseur accounts.
