I am running a dovecot and proxy server on two different virtual machines and
on the dovecot proxy server I see around 5-6 times per day the following

mailboxserver.domain.com took 1.550 s
I do not really understand how from time to time DNS queries are slow, I tried
replicate this issue using dig to resolve the same DNS entry and it was always
very fast. Is there any way I can debug better this issue? or is this nothing
to worry about really?
Maybe the usual network problems?
Did you run a local DNS caching server?
