That depends on the destination_recipient_limit setting, as documented under default_destination_concurrency_limit (default: 20) The default maximal number of parallel deliveries to the same destination. This is the default limit for delivery via the lmtp(8), pipe(8), smtp(8) and virtual(8) delivery agents. With per-destination recipient limit > 1, a destination is a domain, otherwise it is a recipient. For example, local delivery has a per-destination recipient limit of 1, and the concurrency limit prevents one recipient from using up all local delivery processes. Other delivery agents have a per-destination recipient limit of 50 or so, and there, the concurrency limit prevents one domain from using up all SMTP delivery processes. Wietse
