Strange postfix messages [OT?]

[Nejc Skoberne]

Hi.

When receiving mail, my log looks like this:

Jun 10 19:10:43 Illusion postfix/smtpd[22901]: connect from rigljica.arnes.si[193.2.1.82]

I am wondering what "Postfix queue structure is depth 1" means? Maybe
this is not MailScanner problem at all, but Google says completely
nothing about this. Is this somethink like an error?
