Add external DKIM to Vesta DNS

Hello,

I have a few domains hosted in vesta but email is running in Zimbra.
After generating DKIM zimbra records and add the correspondent DNS records to vesta they don't validate.

Domains with mail also in vesta are okay.

Anyone with experience on this?

Thanks in advance.

After some trial and error and stack overflow.

Zimbra Generates something like,
DKIM Public signature:
DDDDDDDD-EEEE-1111-8888-AAAAAAAAAAAA._domainkey IN TXT ( "v=DKIM1; k=rsa; "
"p=......(your_full_key_here)......." ) ; ----- DKIM key DDDDDDDD-EEEE-1111-8888-AAAAAAAAAAAA for domain.tld
Just grab the part from "v=DKIM1; k=rsa; " "p=......(your_full_key_here)......." and ensure that you have everything in one single line with a single space character between the " " like so,

Code: Select all

"v=DKIM1; k=rsa; " "p=......(your_full_key_here)......."
And paste the previous line in to your domain TXT value

After doing so test it with http://dkimcore.org/tools/ - Check a published DKIM Core Key

In the selector input DDDDDDDD-EEEE-1111-8888-AAAAAAAAAAAA and in Domain Name domain.tld

Hope this can be useful to someone else.

Update:

Apparently Vesta does not work with 2048 keys, so anyone interested will have to follow
https://forums.zimbra.org/viewtopic.php?t=60548

And generate 1024 keys instead.
