SMTP Relay Not Functioning


I have been using SMTP to send emails for my XenForo message board for around one year. Everything has worked perfect until now. Perhaps it is to do with the issue in my last thread, in which I encountered DNS issues.

After my question was answered, I went ahead and adjusted all my DNS records to read as follows:

 A                  directs to         3600 (TTL)
NS  directs to   3600 (TTL)
NS  directs to   3600 (TTL)
NS  directs to   3600 (TTL)

Now it seems my SMTP Relay no longer works. For the record, I am with, and have never encountered an issue. I have the necessary ports open and have not changed my account information there.

Thank you

Hi @blackoutro2006 Where does it fail? Are you using Postfix/Exim to relay? Have you checked the logs? Are there any errors/logs in SendGrid? As far as I can remember, you need to setup SPF (and maybe DKIM) on your DNS to allow SendGrid to send mail on your behalf. Did you copy those records over, when you moved to DigitalOcean’s name servers?
