[Case 55171] Adding a long DKIM

[DrunkenBeard]

Hello,

I have to add a long (> 255) DKIM record to my DNS Zone but WHM refuses to let me do that. How can I add a TXT record that is longer than 255 characters either manually or through WHM?

Thanks

Hello,

Where exactly are you hitting this limit?
Is it in WHM => Edit DNS Zone ? or in cPanel => Advanced DNS Editor or in cPanel => Email Authentication?

You can manually edit the zone file via ssh if you need to.

# cp -rfp /var/named/zonefile.tld.db /root
# vi /var/named/zonefile.tld.db

Add the dkim record and increase the serial number.

Then save the file and type:

# rndc reload

That should take care of it. Depending on where you saw this limit, you should open a Feature Request to allow for longer than 255 characters in the dkim field.

Hi,

Thanks for your answer. I forgot to add increase the serial number though and now I can't seem to do any change on the DNS zone (the change appears on the zone file but it doesn't appear if I query the server). What can I do to make the DNS service take my changes into account?

Hello,

You can just go back in and increase the serial number again and save and re-run the
rndc reload

That should update the zone so that when you query it, it will return the correct results.

Hello

I wanted to add that there is an internal case open to add support for TXT records longer than 255 bytes. For reference, the internal case number is 55171.

Thank you.
