I think I already need help :-)
lets take sender_bcc_maps as an example:
lets say I use:
to collect a copy of all outgoing emails at that address. would that work even if I set that email address that collects all BCCs as inactive in ISPCFG3? I'd like to have it inactive as to not receive "normal" emails, would this postfix internal method still work?
The documentation says:
The BCC address (multiple results are not supported)
- what exactly do they mean by that?
