What different domain?
from domain will be example.com and which is fine that’s coming the other will be example2.com and example3.com
Ok, so you pass in example2.com and example3.com for the domain=option for the second and third signers instead of the msg from domain
ok let me try that
local signerl kumo.dkim.rsa_sha256_signer ( domain = option,
selector = 5nXKKHgBnGAcLwvMLZIq’,
headers = ("Content-Type’, ‘Message-Id’,N’Subject’,)
key = '/opt/kumomta/etc/dkim/aclmobile.net/ 5nXKKHgBn.key
msg:dkim_sign (signerl)
please have a look to the configuration
domain = ‘aclmobile.net’
ok let me try
thank it’s working fine
Hello guys
Can you please let me know if double dkim will be implemented based on domian like i want double dkim sign to gmail only
Wtih DKIM policy helper, it’s an all-or-none approach for domains (@yearning-hyena would be great to have it per site as well) . With lua,you can possibly achieve double DKIM signing based on the domain in init.lua.
About deliverability, adding a second (ESP domain) DKIM signature to all emails shouldn’t pose harm from a deliverability standpoint. Providers can still differentiate sender reputation based on their own domain. 
I understand that it would harm but the point is that when I sending the mail to outlook dkim fail although it has double dkim enable
I’ll add that to the roadmap, there may be use cases in the future for signing EC based on destination as well.
There are a large number of senders that double sign to outlook without a problem, if I were you I’d look more deeply for an actual cause for the problem. That said if you’re not using the helper, just add logic to your Lua to check the destination domain and only sign if the destination is not Outlook.
Hi guys can you please help me with the lua script of receiving domain based dkim sign
i tried to do but failure
What have you tried so far? Post your code.
ok posting
