I have the _domainkey.your-domain.com TXT "t=y\;" set in DNS, and it has been a week since we implemented dkim. I have also tested our DNS servers, and I pretty sure there are not any timeouts.

I have found that it does not matter if the format is "Aaron Powell"<ae...@yahoo.com> or not.

If I send to:

netmanss1...@gmail.com, netmanss1...@yahoo.com, ae...@yahoo.com, apow...@st-tel.net, ssei...@st-tel.net

I get dkim=permerror (bad sig)

but if I send to fewer recipients it works. it is like I am limited to a certain number of characters on the to: line, and not necessarily, by recipients.



any other ideas?

Compact Headers

it seems that if we send to three or more recipiants then we get the dkim=permerror (bad sig)

but only if those three are in the format of "Aaron Powell" <ae...@yahoo.com> and not just ae...@yahoo.com.

any help would be appreciated.

Thanks
- dns query timeout from your servers
- an yahoo server have old dns cache of your dns dkim sig

if you just implement dkim or renew dkim sig it better to have a small TTL, and set DNS TXT for
_domainkey.your-domain.com TXT "t=y\;"


Hope that helps you...
