What does Email Error 550 mean?

Follow

Occasionally you may have problems sending emails to employees. Our Mail Log feature is a handy tool to check for any emails that have bounced or dropped. 

A common reason for email bouncing is the 550 error code "Use Mail Relays of your ISP". Basically, this occurs when the senders domain is the same as the recipients domain, e.g. the sender has @example.com and the receiver has @example.com as their email address. Depending on the settings at your mail servers end, it will cause problems.

The problem is that we're impersonating 'example.com' when we send emails, and so when we send them to another 'example.com' address, the receiving mail server at 'example.com' goes, "hang on a minute, we didn't send this to ourselves! Someone is trying to impersonate us and that looks dodgy and is probably spam, so let's bounce it". 

There are 2 ways forward in order to have the emails successfully sent and received:

1. You can relax the rules at your receiving mail server to accept mail that has a From address of 'example.com' but was not sent by 'example.com'. Before doing this we recommend getting advice from your IT department. 

2. You can change the contact email address in the Pay Slip configuration to be something not 'example.com'

3. You can add sendgrid (the people we use to send emails with) to your spf DNS record. This is done by adding `include:sendgrid.net` to your spf DNS record
