What's odd is no matter what I do the 'envelope to' info when running
'exim -bt -d foo-request@???' never changes. This was very confusing
as the actual delivered mail actually does change 'Deliver-To:'.
This sort of works. The errors_to in the router never sets the field, so
I added it to the transport.
Now I'm trying to figure out how to do something like:
if ($the_original_local_part =~ /*-request@*/) {
return_address = $local_part%$domain@$sender_address_domain
return_path = $return_address
headers_add = "Errors-To: $return_address"
}
This is required so only recipients containing '*-request@???'
have their Return-Path and Errors-To munged to the VERP address.
Suggestions?
# router
verp_dnslookup:
driver = dnslookup
local_part_suffix = -request
#local_part_suffix_optional
#errors_to = $local_part%$domain@$sender_address_domain
debug_print = " local_part = $local_part"
transport = remote_smtp
no_more
# transport
remote_smtp:
driver = smtp
max_rcpt = 1
return_path = $local_part%$domain@$sender_address_domain
headers_remove = "To:Errors-To:"
headers_add = "To: $local_part@$domain\n\
Errors-To: $local_part%$domain@$sender_address_domain"
