Secondary DNS is not up to date

Question

I have a primary DNS on my FreeBSD server ns0.dddddd.eu and secondary DNS on Xname.org.

But secondary DNS's on Xname.org are not up to date! Commands """#dig @ns0.xname.org dddddd.eu mx"""" and ""#dig @ns0.dddddd.eu dddddd.eu mx"""" return different answers! NS-servers servers do not see my MX-record mail2.dddddd.eu. Why? Please help me!

#dig @ns0.xname.org dddddd.eu mx

Your zone serial number 1 looks suspicious. You should update it every time when zone file changed or secondary server will not update. It is recommended to use something like 2010082201 for serial number.

xname is historically known to be extremely slow to synchronize DNS data from your master.

If you look for something with quick sync, BuddyNS auto-syncs in 10 minutes, or immediately if your master supports NOTIFY. That's secondary-only, so you need indeed your primary DNS to use it.
