When your settings seem to be correct and the emails are going out from our end, it means they are either being rejected by your email provider or put in a spam folder. We are unable to make it go past these filters. However, you may be able to do a couple things on your end:
- try to find out if the email is placed in a spam box either on your email software (if using one) or on your email provider's webmail interface (the spam folder for both are different) and mark the emails as non spam if you find them.
- since the email may have been rejected outright by your email provider without even making it to spam folders, you can see if there's a way to whitelist our email@example.com address or our primary email server's IP address (220.127.116.11).
- you could send an email to firstname.lastname@example.org (it doesn't matter what it says, it won't be read) as this action sometimes has the effect of whitelisting it for either your email software, your email provider or both.
