HI
I had a problems with my DNS server and had got my Glue records changed towards my primary DNS on last Thursday evening (24/5).
Now majority of the nameserver are resolving my mail server bic.boseinst.ernet.in as 14.139.199.26 but some like google(8.8.8.8) is resolving it as my old ip of the server (202.141.148.26) hence i am not able to get mails from gmail (but no mail is returned back to gmail niether do i recieve it). But 8.8.8.8 has already updated my websever to new address (14.139.199.26). What should be done so that the new mail server address gets updated and i get the mails.
Thanking you

Hi,

It depends how you changed the DNS A record and what TTL value it had before changes (if it was 1 week, then you will probably need to wait 1 week for DNS changes to take effect).
Do you have a cPanel for managing the server or did you do it manually by editing zone file (bind/named config) ?
If that is the case, can you post your zone record (change IP's and names before posting)

Found the DNS initially pointing to wrong IP
