Hi, I have ispconfig 3 installed on a master server and a standalone mail server. For simplicity I will call these domain.com and mail.domain.com I am having trouble getting the dkim to work in enom DNS. So my domain passes off mail to the mailserver, I have the correct spf saying that mail.domain.com can send mail for this doman, the dmarc is also working as expected. The trouble I am having is the DKIM record, MXToolbox just cannot find it even though its right there in the Enom host records. The dkim record is as follows: selector._domainkey.domain.com with TXT v=dkim1 etc etc etc I have validated the dkim key using https://dkimcore.org/c/keycheck and all "should" work but the dns is just not found, its well past any propagation time that might be needed. Should the dkim record be selector._domainkey.mail.domain.com dkim is installed on the both the master and the mail server so this is the reason I ask. Failing that, has anybody else gotten their dkim to work with enom, if so, can you shed any light on this as it might be something they have set, key length maybe, im just at a loss this has been a problem for me for a couple of weeks now and nothing seems to help.
