Simple Procedure to test when customer complains "cannot send email".
Try to email yourself @creativecomputing.com.au email address. If it works, get user to try emailing to an external account, not their company account. This means their email host is rejecting emails from Control.
Setting up SPF record.
Following email has been sent to all customers using SAAS and hosted in Control: I first look through their branch records and find out if the email address is set. Then I look at the employee records. Noting down domains of the email addresses, as Control use these as the "From:" address when sending out email (looks in employee first, if that is blank, will use branch email).This is an example email:
- I have recently been looking into how we send emails from Control. Over the last few years people have done a lot to combat spam. What has then happened is, settings that are supposed to be "optional" are now set up by certain email hosting providers as "mandatory".As a result, emails sent to these domains are hit and miss, but most of the time, they bounce back.
Can you let me know what domains you use to send email "From" Control I think you have "customers.email.domain", not sure if there are others. Once you have these, I need you to get people in charge of your domain(s) to create a SPF record and add these IP addresses to it:
ip4:220.233.88.72
ip4:139.144.96.181
ip6:2400:8907::f03c:93ff:fe7e:d20a- Your DNS guys should know what to do with the above. If not, please let me know how to get in touch with them (or have them contact me) so we can sort it out.
The 3 addresses are as follows: 1st one is our current head office ip address (exetel). 2nd and 3rd is our cloud hosted mail relay.
To do a quick test, enter the following command (in a linux prompt, maybe on sam):
dig txt <domain to test> @8.8.8.8
If the domain has been set up you should see a line with the above 3 IP's set up.
