Value of $address_data is also available in acl_smtp_rcpt after
evaluation of verify = recipient. Very handy for per recipient options.
First local delivery router looks like:
address_data_fill:
debug_print = "R: address_data_fill for $local_part@$domain"
driver = redirect
domains = +local_domains
address_data = FILL_ADDRESS_DATA_MACRO
data = :
Later routers, transports (with restrictions Phil wrote about) and post
verify = recipient ACL stanzas do string expansion like
${extract{attr_name}{$address_data}{$value}{}} to extract data from this
very one variable.
