Michael Sharp Posted February 16, 2022 Share Posted February 16, 2022 Hi all, have been asked whether Hornbill is DMARC compliant and wanted to get further information around this? https://www.dmarcanalyzer.com/approach-vendors-dmarc-related-questions/ Regards and thanks, Mike.

Gerry Posted February 16, 2022 Share Posted February 16, 2022 @Michael Sharp To the best of my knowledge we are, our mail system supports both SPF and DKIM which are the two things that DMARC requires from a functional standpoint. I do not believe you need anything else. Gerry Link to comment Share on other sites More sharing options...

Michael Sharp Posted March 3, 2022 Author Share Posted March 3, 2022 @Gerry I've got this back from Mimecast sorry? hornbill.com is categorized as "Authorized Not Compliant", with the reason that we will also need this source to be configured with DKIM. If you are going to have an occasion where emails get automatically forwarded, alignment with SPF will not be achieved, whereas with DKIM it can. Kindly complete that part by requesting the vendor to provide a public DKIM key for your **REDACTED** domain to publish into your DNS. That way, it can be regarded as an Authorized Compliant source when your emails get signed with DKIM. Hoping this means something to you? Given the nature of the query, might be worth taking this to a DM chat? Regards, Mike. Link to comment Share on other sites More sharing options...
TrevorKillick Posted March 4, 2022 Share Posted March 4, 2022 @Michael Sharp I beleive this post from Gerry prevously showing our DKIM support for each domain connected to a hornbill instance is what you are looking for: Thanks Trev Link to comment Share on other sites More sharing options...
Gerry Posted March 4, 2022 Share Posted March 4, 2022 @Michael Sharp As far as I understand it, If **REDACTED** is your domain, this is something you would need to do on the DNS servers that host your domain. The hornbill platform makes it possible for your instance to be configured in relation to email to be DMARC compliant because we support both DKIM and SPF, but our own email, that is emails that come from Hornbill.com for example, to the best of my knowledge is not specifically DMARC authorized, although we do use both DKIM and SPF Gerry Link to comment Share on other sites More sharing options...
