Isaac Asher Posted February 12, 2022 Share Posted February 12, 2022 (edited) Recently installed OX App Suite again (I LOVE it!!) but whenever I send an email to a Microsoft 365 account, it shows a question mark next to my name and strips out all the html link functionality. After a bit of research, I think it has something to do with the way the DNS is set up and preventing spoofing. According to the Microsoft docs, it seems that my OX App Suite email address is not authenticated in the way that Microsoft expects. Could not find good documentation on how to correct this issue. Seems Microsoft thinks OX App Suite emails are spoofed and I'm not sure what can be done to correct this without breaking OX App Suite. Does anyone know if there is an additional DNS entry that would correct this issue (or some other fix)?

WHMCS Support Manager WHMCS John Posted February 12, 2022 WHMCS Support Manager Share Posted February 12, 2022 Hi @Isaac Asher, I'm glad to hear you like the OX Service. The first thing to check is that the recommended SPF record is set up for this domain: https://marketplace.whmcs.com/help/connect/kb/ox_app_suite/getting_started/what_spf_records_should_i_use 0 Quote Link to comment Share on other sites More sharing options...
Isaac Asher Posted February 12, 2022 Author Share Posted February 12, 2022 Hi @WHMCS John! You've bailed me out of many sticky situations in the past. Always appreciative! I checked the DNS on that domain and found that I have the same DNS entry as installed by the OX App Suite setup script. There are a few differences, however. The TTL on my entry is 14400 whereas the example showed 3600. The name on my entry shows the domain name and TLD, whereas the example says to use an at-sign or blank. I tried to change the name to blank and cPanel said the field is required. Tried to use an at-sign and it said it was an invalid character. Can only be alphanumeric. No choice but to leave the Name setting to what it originally was (my domain with TLD). Was able to change TTL from 14400 to 3600 without issue. Sent another email and same results; grey question mark and links disabled. 0 Quote Link to comment Share on other sites More sharing options...
WHMCS Support Manager WHMCS John Posted February 23, 2022 WHMCS Support Manager Share Posted February 23, 2022 Hi @Isaac Asher, I've updated the SPF article with a sample SPF record from cPanel. It took me a while, but I managed to dig up an explanation of the question mark icon you were seeing in O365 and its meaning: https://docs.microsoft.com/en-us/microsoft-365/security/office-365-security/set-up-anti-phishing-policies?view=o365-worldwide#unauthenticated-sender It appears that creating DKIM records for the domain might prevent this from occurring. Currently DKIM keys aren't available from OX for custom domains like this, but I've noted this down with the product team for investigation with the vendor in future. In the meantime, Microsoft's document above indicates that the recipient can add the domain to a safe senders list to remove the ? 0 Quote Link to comment Share on other sites More sharing options...
ShahidMalla Posted March 29 Share Posted March 29 there still no DKIM support 0 Quote Link to comment Share on other sites More sharing options...
Mandalorian Posted March 29 Share Posted March 29 How can you provide an Email Service without DMARC support? This issue renders the whole OX Suite unusable and unsuitable. 0 Quote Link to comment Share on other sites More sharing options...
