I have 2 questions and I think they are both related and should be simple answers.
I run ISPConfig on a server with a couple of domains and DNS is setup through my registrar. Now I have set up google apps for email. The individual websites also send emails (order notifications etc). I followed the google directions for changing the mx records at my registrar but I still see one old mx record:
Your MX records that were reported by your nameservers are:
0 mail.anaselectronics.com No A Record (no glue either)
10 aspmx.l.google.com 18.104.22.168 (no glue)
20 alt1.aspmx.l.google.com 22.214.171.124 (no glue)
30 alt2.aspmx.l.google.com 126.96.36.199 (no glue)
40 aspmx2.googlemail.com 188.8.131.52 (no glue)
50 aspmx3.googlemail.com 184.108.40.206 (no glue)
1. Where is this old 0 priority record coming from? I have not yet changed reverse PTRs, did reverse PTR automatically add a mx record? or does ispconfig broadcast dns?
Note that the email is coming through fine since there is no A record for mail.anas so the correct google records get used, but google thinks my dns is not setup correctly and also the blackberry service doesn't recognize this email address as a google account. I think clearing out that first record will correct both these issues.
2. What should be the correct reverse ptr for my IP(s) now that I am using google apps for email; my server does send emails using sendmail.
