Ryan Magdaleno Posted October 18, 2020 Share Posted October 18, 2020 I use proton mail for my personal email as well as all email related to my site. Nothing sent from IPS (registration emails etc) makes it through to proton mail. I've tested with gmail which is working fine. Is this likely a problem with proton mail, my server's email configuration, or with IPS itself? Given that gmail works I'm tempted to rule out my server config but want to be certain.

bfarber Posted October 19, 2020 Share Posted October 19, 2020 It may very well be your server or the provider. There are configurations such as DKIM and SPF that one provider may need set up which another doesn't, for instance. Link to comment Share on other sites More sharing options...
CoffeeCake Posted October 19, 2020 Share Posted October 19, 2020 If you are sending using local smtp on your server, check your smtp mta's logs to see what protonmail is sending in response to e-mail requests. If you're using a third-party SMTP service, look into how to see mail logs via your provider. As @bfarber mentioned, you'll want to verify your server isn't on any spam blacklists, and that you have setup correct DKIM/SPF/DMARC records. https://mxtoolbox.com/ is a tool out of many that you can use to validate all that. Start with your logs first. Link to comment Share on other sites More sharing options...
