SOA serial still not match.

Dear Mrat,
Let's me tell you from beginning
Two week ago, my vps were be DDOS attack ( i guess so ), RAM Available <100MB (my VPS has 3.5 Gb Ram), MySQL stop working and website cannot access, it's show cannot connect to database, error (2).
i installed CSF firewall and now VPS working smoothly (maybe they don't want DDOS again)
Before installing CSF, i can send or receive email as normal. now i'm disabled CSF but i'm still send email to gmail/hotmail...
My mind i didn't change anything, exception installed CSF.
For SOA serial not match, could you tell me how to fix it?
Thank you.
