[SOLVED] DKIM

[eistek]

I am using plesk server for hosting my domains and plesk server is using PMG server as smarthost.

I have acticated DKIM signature on plesk server. Do i need to enable DKIM on PMG server too?

Or would i disable DKIM signature on plesk and enable on PMG?

If the current signature scheme works - you can stick with it.

The issue with DKIM signing before the mails leave your system is that PMG could change the mail (if you e.g. add a disclaimer...) - and this might render the DKIM signature invalid

In theory you could sign the mails on both places - but I don't see where this would be an improvement (if all outbound mails pass through PMG)

so in short: if it works as it is currently - why not leave it at that...

I hope this helps!

dkim=pass header.i=@blabla.com.tr header.s=pmx header.b=eLhoqTdX;
dkim=pass header.i=@blabla.com.tr header.s=default header.b=UiIq4w6

Google is checking both dkim signature. s=default is my plesk server s=pmx is my proxmox gateway.

Thankyou
