Re: Add header based on number of recipients

[Jan P. Kessler]

With postfwd you could use the following rule:
id=RCPTCNT
    action=PREPEND X-RCPT-COUNT: $$recipient_count

or something like that

id=RCPTCNT01
    recipient_count>=200
    action=PREPEND X-RCPT-COUNT: RED

id=RCPTCNT02
    recipient_count>=100
    action=PREPEND X-RCPT-COUNT: YELLOW

Please note that postfwd must be used at DATA or END-OF-MESSAGE stage to 
get recipient_count reliably.
