Thanks for your comments. I understand as DNS uses UDP that there could be some DNS queries which might get lost if the CPU or network is too busy but the thing is that this server is not so busy really. It has 2 cores with 4 GB of RAM and the CPU averages to 2% usage. The network averages to 1

how do you come to the conclusion that it matters how busy "this server is"? jesus christ you are asking *remote servers* for their answers and the request as well the answer passes different routers, ISP's and likely a *chain of forwarders* until you don't recursion at your own and even if you

My fault here, I should have precised that the DNS query it tries to resolve is simply the DNS name of my mailbox server (mailboxserver.domain.com). So domain.com is hosted locally on DNS servers on that very same network as the dovecot servers are located. Furthermore all the resolvers I use i
