              Hello,
two months ago emails completely stopped working on my Discourse site. No activation emails are being sent and no emails are being received by regular users with summary of new posts.
I would be willing to pay someone to fix it for me.
Thank you

Then you should post in Marketplace 
But the first place to look is at your email service and see if your account is in good standing. Probably your credit card expired or something like that.

              Ok, I will post there.
My account is in good standing. However, I know nothing about IT so I don’t know what is wrong. The emails just stopped working one day.
I am using MailGun and all is paid.
             
            
              
            
           
          
            
            
              do you have administrative access?
Find Admin in the left side bar (on mobile the hamburger)
tab thru Skipped, Bounced Rejected and there is an error message

When I try to test sending of e-mails, it shows this error:
“ ERROR - execution expired “

              On MailGun, there is no sending key, maybe this could be the reason:
             
            
              
            
           
          
            
            
              
it timed out?
 Sukenik:
 
there is no sending key,
 
 
maybe key expired?once it gives you a new key, you will probably need to add it to your site settings

              I think that Mailgun needs to get somehow re-synced with Discourse but I don’t know how to do that so will need help from someone experienced.

              The issue was that digital ocean has started blocking outgoing access to port 587,so I changed it to port 2525.

              I also use Digital Ocean and Mailgun. How can I check whether this is or might become a problem for me? Thanks.

              If your mail inexplicably stopped working, this is almost certainly the reason.
Edit your app.yml and change the smtp port to 2525. Then
./launcher destroy app ;./launcher start app
If you don’t know what that means, you can run discourse-setup, hit return a bunch of times and change the port and let it rebuild.
