Hello,
I'm currently testing the A.11 section, blocking collateral spam.
In A.11.1 we have:
remote_smtp:
debug_print = "T: remote_smtp (hashed) for $local_part@$domain"
driver = smtp
max_rcpt = 1
return_path = ${local_part:$sender_address}=$local_part=$domain=\
${hash_8:\
SECRET=${local_part:$sender_address}=$local_part=$domain}\
@$qualify_domain
The $qualify_domain is a sure killer in any mail system handling more
than a single domain and likely even in some with not just one but
multiple servers.
I replaced the last line with this, resulting in much more generic
solution:
return_path = $sender_address_local_part=$local_part=$domain=\
${hash_8:\
SECRET=${local_part:$sender_address}=$local_part=$domain}\
@$sender_address_domain
As a side note, the above transport will only be called in my setup
for addresses aka users that selected this option, not forcing the
max_rcpt and computational slowdown onto everybody. :)
Regards,
Christian Balzer
