Hi I am using roundcube to route my emails for my domains and I am trying to get my emails signed with DKIM. I have generated the keys I need for the DNS records on my domain, but there is a private and a public key and I am not sure which one to use. The website I generated the key on seems to suggest the private one is needed. I have added this kid at the moment, but the DKIM has not yet been implemented (I know this is not instant and can take some time). Does anyone know which record I should be using? Also, does anyone know how long this normally takes to run through the system and finally is there anyway I can easily check if it has been applied to my DNS settings? Many thanks in anticipation. Matt
What kind of mail server do you use, and which software are you using for DKIM signing? Do you use any control panel or other software to manage your server?
Hi Till I think 123Reg is my mail server (which is where my website is hosted). I do have a control panel, this is where I managed to enter the DNS record, at domain level. Regards. Matt
Roundcube to manage mail routing?? Roundcube is a webmail client only, to get webbased access to your IMAP mailbox. It's not a MTA. On linux based systems OpenDKIM in the older days and Rspamd nowdays are the most common DKIM signing applications. Both need to be implemented into the MTA (like Postfix) to do the DKIM signing of mails. Also, both have commands to be used on the command line to create private and public keys for signing. The private key is NEVER to be published in DNS (or anything else for that matter). It's PRIVATE.
