For specific 2 recipients of our domain, we don't want always_bcc to be
implemented. ie. if a mail is addressed to a...@xx.com (our domain only),
mail should not be Bcc to zz...@xx.com. similarly if mail recipient is
d...@xx.com (our domain only), mail should not be Bcc to zz...@xx.com. For
all others always_bcc to continue.
Suggested approach (this uses "inline" tables, but equivalent file-based
PCRE, or, in the case of the transport(5) table, hash or cdb tables also
work.
main.cf:
recipient_delimiter = +
recipient_bcc_maps = pcre:{
{ /^"(.*)"@example\.com$$/ "bcc+$${1}"@example.com }
{ /^(.*)@example\.com$$/ bcc+$${1}@example.com }
}
transport_maps = inline:{
{ bcc+...@example.com = discard:silently }
{ bcc+...@example.com = discard:silently }
}
The "$$" syntax is only needed for inline tables in main.cf, just a
single "$" is needed in a file-based PCRE table
rcpt-bcc.pcre:
/^"(.*)"@example\.com$/ "bcc+${1}"@example.com
/^(.*)@example\.com$/ bcc+${1}@example.com
