v1.0.1

Added

• External alias targets — /alias_add now accepts a full email address as the mailbox, so aliases can forward outside MAIL_DOMAIN, e.g. /alias_add support someone@external.example. A bare local part still resolves to MAIL_DOMAIN, and a full address on MAIL_DOMAIN is treated as local.
• /alias_delete and /alias_list [mailbox] also accept full external addresses.

Fixed

• /alias_add no longer creates dangling aliases that bounced mail at delivery: a local target must exist as an account or another alias (verified against the container's account and alias databases) before the alias is created.
• /alias_delete now reports when the requested alias → mailbox mapping does not exist, instead of asking for confirmation and silently deleting nothing.
