Yes, with the proviso that if different recipients are associated
with different auto-response message bodies, or if auto-reply.pl
for some other reason needs to send separate messages to the original
sender for each original recipient, then the qmgr settings for
"vacation" transport should include:
vacation_destination_recipient_limit = 1
vacation_destination_concurrency_limit = 2
Choose your vacation destination with care and book early! :-)
