Hello, Postfix logs to syslog the number of recipients in the "nrctp" field.
The nrcpt field reports the number of recipient after the expansion (ie: by virtual table).
A field reporting the number of recipients written by the client (number of "RCTP TO") could be very useful too, to perform data analysis.
If this is already possible, I would ask an help to configure Postfix in order to obtain this log. Otherwise, I thank you very much if you could consider to add this feature in future.
Today, I can obtain this information grouping all logs with the same queue_id and counting the different "orig_to" fields, where they are present. So it is possible, but the operation is quite complex.
Many thanks Cheers Marco
