Check if a domain is services by GMail for Business (former Google Mail for your domain)
Posted by jpluimers on 2018/06/15
Anyway: at the time of writing it is at https://gsuite.google.com/products/gmail/.
If you send mail to such a domain and the user doesn’t exist, you get a confusing error message like this:
<<< 550 5.1.1 https://support.google.com/mail/?p=NoSuchUser [^] j191si981824wmd.134 - gsmtp
So I wanted to test if a domain is being services by gmail and found this StackExchange question:
Basically you can test it in two ways:
- on a web-page at [Archive.is] Google Domain Tester
- using a DNS query for the MX servers, for instance using
digas shown here:
dig takeheart.com mx
takeheart.com. 86399 IN MX 20 ALT1.ASPMX.L.GOOGLE.com.
takeheart.com. 86399 IN MX 30 ALT2.ASPMX.L.GOOGLE.com.
takeheart.com. 86399 IN MX 10 ASPMX.L.GOOGLE.com.
takeheart.com. 86399 IN MX 40 ASPMX2.GOOGLEMAIL.com.
takeheart.com. 86399 IN MX 50 ASPMX3.GOOGLEMAIL.com.
