Emails not getting through.
Symptom: questionnaire emails sent to colleagues using company email addresses are not being received, but emails sent to outside email addresses such as email@example.com are getting through with no problem.
Cause: The company mail server is incorrectly classifying the emails as junk mail and is blocking them.
Solution: In the first instance you should ask your colleague to check their junk email to see if the email ended up there. If still no luck our emails will need to be recognised by the company firewall as coming from a safe sender – the IT dept will be able to do this with the information below:
Our sender email addresses: firstname.lastname@example.org, email@example.com
Our sending server IP addresses:
- 188.8.131.52/27 (184.108.40.206 – 127)
- 220.127.116.11/26 (18.104.22.168 – 255)
By default we send emails using the “on behalf of” format so that they appear to be coming from the person who is running the 360 project. However, some mailservers regard this as spoofing and reject the emails. If this is happening we can change the email header so that the emails appear to come from @appraisal360.co.uk and this normally clears this problem.
