Mailgun or Mandrill users - my email got blocked?


Well-known member

I'm having a problem and hope someone knows what am I doing wrong.

I was using Mandrill, but now I'm on Mailgun. But here now starts same problems.

So, what's the big deal.

All my users are getting emails from my forum normally, only I don't! Ok, now I've changed my admin email to something else (before I was using the same one as my forum email address).

Now the problem persist only when trying to post via contact form. It sends from same email address to same email address (my forum email!) - that email got blocked!

Sorry, I hope you understand what am I trying to say...

Question: are you using same email for forum email address and for your admin account?

Ok, just changed my contact and admin email address to something else that is not on same domain (used gmail account instead). But still don't know what is the issue.

No, I'm using SMTP.
If you use postfix to send out the emails (via smtp) you can check logs to see what is happening with your url. I've never used Mailgun so can't comment on how to set that up. I use SendGrid via Postfix and it works perfect.

Yes, as I said, if it's send to different email (not with my domain!) it is ok.

I just changed my contact and admin address. But still don't get it. This should work with emails on same domain.

Ok, I got an answer from official support (Mailgun):

Sorry about that, it looks like a noisy sender on the IP caused it to become listed on a blacklist. I've gone ahead and moved you to a new IP while we work to get the previous one de-listed.

So if anybody's dealing with same problem...
