Nigel,

thanks for your e-mail. It gave me a big "ahaaa" but unfortunately
I am still a little bit confused:

According to this link, the default for batch_max is 1 which should result
in no batching at all. However we have not used batch_max so far in
our local transport:

local_delivery_mysql:
driver = appendfile
delivery_date_add
envelope_to_add
return_path_add
#group = mail
#user = mail
mode = 0660
directory_mode = 770
mode_fail_narrower = false
maildir_format
directory = ${lookup mysql{MYSQL_LOCALUSER_HOME}{$value}{'fail'}}

Thus, we assume that the default of batch_max is active (1) but we still
see e-mails with multiple recipients pointing to the same postbox
only once.

Happy for any advice
Sascha
