Detailed and helpful test report for running your own email service
Unlock The Inbox kindly provides me with a free email test, which gave me very detailed and helpful report on various settings, such as DNS, SMTP, IMAP, SSL, SPF, DKIM, DMARC, etc. The report highlights the critical problems and reminds the possible warnings/issues, which is really helpful.
One missing thing from the report, I think, is the open relay check, but Unlock The Inbox provides such check on a separate URL for free.
Thanks to Unlock The Inbox for their great service.
