postfix recipient_bcc_maps multiple recipients how to?

Question

is it ever possible to have multiple recipients in /etc/postfix/recipient_bcc_maps ?

/etc/postfix/recipient_bcc_maps :

source@domain.tld recipient1@domain.tld

Can I do something like:

**source@domain.tld rcpt1@domain.tld,rcpt2.domain.tld,rcpt3@domain.tld**

Googling with no success whatsoever

Answer 1

You cant specify multiple recipients in the right hand side of the recipient_bcc_maps. So

source@domain.tld    rcpt1@domain.tld,rcpt2.domain.tld,rcpt3@domain.tld

is not possible. But The BCC address is subject to virtual alias expansion (and aliases(5) expansion for any resulting local recipients). So

#/etc/postfix/main.cf
#...
virtual_alias_maps = hash:/etc/postfix/vmaps
#...

#/etc/postfix/recipient_bcc_maps
source@domain.tld    rcpt@domain.tld


#/etc/postfix/vmaps
rcpt@domain.tld    rcpt1@domain.tld,rcpt2.domain.tld,rcpt3@domain.tld

should help you to achieve it.
