Last week all of my email alerts stopped getting sent out for some reason, I checked what I know to check and couldn’t find anything obvious. I restarted the gateway and the e-mails started working again for a few days and then stopped again. I’m not sure what’s going on with it as I haven’t added any new e-mail alerts lately.
What should I be looking for to try and identify the problem? It’s hard to tell when it stops working because everything else looks fine. Any help to point me in the right direction would be much appreciated, thanks!
